How to remotely access the Desktop of your Raspberry Pi over the internet

VNC is a tool for accessing your Raspberry Pi graphical desktop remotely. Setting up VNC is really easy but it usually only gives you access from another computer that is on the same network as your Raspberry Pi.

In this article we will guide you through how to use PiTunnel to allow you to access a VNC remote desktop for your Raspberry Pi from anywhere in the world. We will do this by using the Custom Tunnels feature of PiTunnel. All your Raspberry Pi needs is an internet conection and PiTunnel will do the rest.

What is PiTunnel?

PiTunnel is a service for remotely accessing your Raspberry Pi, and the projects that you build on it. A Device Monitor and Remote Terminal is included, and you can also create your own Custom Tunnels to access services running on your Raspberry Pi.

Enabling VNC Server

The first step is to enable VNC server on your device. The easiest way to do this is as follows:

  • Open a terminal on your Raspberry Pi or use the PiTunnel Remote Terminal.
  • Enter the command sudo raspi-config
  • Use the arrow keys to select Interfacing Options and press Enter.
  • Use the arrow keys to select VNC and press Enter.
  • You will be prompted to enable VNC Server. Select Yes and press Enter.
  • Use the arrow keys to select Ok and then Finish, to return to the terminal.

Installing a VNC Viewer

You will need to install a VNC Viewer on your computer, so you can connect to you Raspberry Pi. There are a number of viewers available, but the easiest to set up is Real VNC Viewer. You can download Windows and Mac installers from here: https://www.realvnc.com/en/connect/download/viewer/

Testing your server over your local network

troubleshoot, connection, refused, black, screen

After you have installed a VNC Viewer, you should test that you can connect to your Raspberry Pi on your local network. You should do this before setting up the tunnel for remote access, to check that everything is installed correctly.

  • Open Real VNC Viewer.
  • Enter the address “raspberrypi.local:0”, where “raspberrypi” is the hostname of your device, and press Enter. NOTE: Please make sure that your Raspberry Pi is not using the default password ‘raspberry’, so that your device is protected from unauthorized access.
  • Enter the username and password for the raspberry pi login. For example username “pi” and password “raspberry”, and press OK.
  • The VNC session should start, and you should see your Raspberry Pi desktop.

Creating a tunnel to access VNC remotely

Once VNC is running, and it is accessible on your local network, you need to create a custom tunnel so that it can be accessed through pitunnel.com. A custom tunnel allows you to access your Raspberry Pi VNC through PiTunnel.com with an address like pitunnel.com:12345.

Custom tunnels are created by entering a command in your Raspberry Pi terminal: pitunnel.-port=5900.-name=vnc In the above command, 5900 is the standard port number used for VNC. For most users, you should be able to enter the command exactly like that.

After you run the command, you will see the following output in your Raspberry Pi terminal:

pitunnel.-port=5900.-name=vnc Connected to Tunnel Server pitunnel.com, v1 Waiting for Client connection

Testing your tunnel

  • Go to the Custom Tunnels page and find out the world-wide accessible address for your tunnel.
  • Open Real VNC Viewer and enter the “Available At” address from PiTunnel.com into the address field.
  • If you are asked about Duplicate VNC Server identify, press Continue.
  • Enter the username and password for the raspberry pi login. For example username “pi” and password “raspberry”, and press OK.
  • The VNC session should start, and you should see your Raspberry Pi desktop.

Making your tunnel persistent

Once you have tested that your tunnel works, you will probably want to make it perisistent. This means that the tunnel will load automatically every time your Raspberry Pi powers on, and stay active even if you close the terminal window.

To make a tunnel persistent, add.-persist to the end of the command line options:

pitunnel.-port=5900.-name=vnc.-persist Created Persistent Tunnel Current Persistent Tunnels:. | ID | Command-Line Arguments |. | 1 -port=5900.-name=vnc |.

For more information about creating and removing peristent tunnels, please see the Persistent Tunnels section of the documentation.

Troubleshoot: VNC connection refused, VNC Black Screen Issue and many others

Virtual Network Computing (VNC) is a screen sharing mechanism that makes it possible to remotely control another computer. Making use of the RFB (Remote Frame Buffer) protocol – VNC allows for the transporting of data between the server and client machines.

This includes peripheral inputs and outputs from your keyboard and mouse, making the VNC experience behave as if you’re physically connected to the server. The server is the remote device that you want to connect to. Client refers to your local machine from which you are accessing the server. Check other best secure remote access software.

The most common problems experienced by VNC users involve connectivity errors and display issues. This article will guide you through these common problems and provide you with recommended steps to resolve these issues.

VNC Server is Not Currently Listening for Cloud Connections

  • The remote computer or server must be connected to the Internet in order for you to connect to it.
  • Make sure that the server is not in sleep mode. It is recommended that you configure the power options to ensure it never goes to sleep.
  • Is “Allow Cloud connections” checked in your VNC Server settings?
  • Have you selected the correct team for the remote computer?
  • For subscription users, verify that you are attempting to join your computer with the correct paid-for team.
  • If you’re using Linux, establish that the Linux display server protocol Wayland is disabled.
  • Сheck the RealVNC status page for service issues
  • If none of the previous steps helped, restart the VNC Server itself and the computer, which is running it.
  • If you have gone through all the above steps but you are still experiencing a problem, then log a support ticket with RealVNC here.

    VNC Viewer the Connection was Refused by the Computer

    Reasons why you may get a “connection was refused” error:

      The VNC server is not running

    Make sure you log in with the correct user/password combination. When running the vncserver command, set the password as the correct user. Also make sure the server is started by using service vncserver start.

    VNC Connection Refused 10061

    Possible reasons why you’re experiencing this problem:

    Kali Linux VNC server moniter X1-lock problem fix termux

      VNC server is not running Simply restart the service using the “ service vncserver start ” command.

    Unable to Connect to VNC Server Using Your Chosen Security Setting

    Common reasons for this error include:

      The encryption settings for a direct connection between the Server and the Viewer are not compatible.

    troubleshoot, connection, refused, black, screen

    Sometimes you can see the “ No Matching Security Types ” error message because of these reasons.

    To try to resolve this, check for the latest versions of the VNC Connect and VNC Server applications and make sure to upgrade accordingly.

    If that doesn’t resolve the problem, change your VNC Server encryption parameter to one of the other settings other than AlwaysOff. Also change the VNC Viewer Encryption to Server, PreferOn or PreferOff.

    VNC authentication failure

    If VNC Viewer error ”The too many authentication failures” is experienced, this could indicate that someone is using brute force attacks to try and gain access to your server.

    If you need to regain access to your VNC, follow these steps:

    To prevent this from happening again, block all public IPs on your firewall with exception to those known / required IPs. This however will only work with static IPs.

      To list your current active firewall rules, use #iptables.L.

    VNC connection closed unexpectedly

    If you get a “Connection closed unexpectedly” error, check the following:

      Make sure the VNC server and clients are allowed by the firewall.

    If previous steps didn’t work, you need to check the logs. An “Error during RFB initialization” means that you need to uninstall all display drivers incompatible with the VNC Server.

  • Choose VNC Server as the Event sources.
  • Another reason for this error may be because your version of Windows and VNC are incompatible. If you’re on Windows 7 or above, your version of RealVNC must be v5 or greater.

    VNC Connect Review

    VNC Connect can get the job done, but it’s confusing to set up and falls short of other remote access software in terms of performance, pricing, and feature set.

    • Free version for home use
    • Quick and reliable connections
    • Mobile support for remote viewing


    • Low frame rate compared with other apps
    • Confusing to set up
    • No built-in audio chat, video chat, or whiteboard

    Explaining what VNC Connect is requires using the letters VNC a lot, and it can be confusing. VNC stands for Virtual Network Computing, which is an open-source protocol for remotely controlling computers. VNC Connect comprises remote access software and a Cloud service offered by RealVNC. To use VNC Connect, you need the RealVNC Viewer app and the RealVNC Server app. It can be bit confusing. Name quibbles aside,VNC Connect can get the job done but can also be difficult to set up and performed poorly in our tests compared with other remote access applications.

    What’s The Difference Between VNC Connect, RealVNC, and TightVNC?

    As mentioned, VNC stands for Virtual Network Computing, an open-source protocol for remotely controlling computers. Most Linux distributions and even macOS come with a version of this VNC protocol built-in. RealVNC is proprietary software that uses this open-source protocol. VNC Connect is the subscription service that enables Cloud connections—it’s the subject of this review.

    troubleshoot, connection, refused, black, screen

    RealVNC, the company that makes VNC Connect, has been around since 2002, founded by members of a team at ATT that invented the VNC protocol in the 90s. It’s a strong pedigree, and no small part of why the letters VNC are synonymous—by those in the know, at least—with remote access software decades later.

    Since 1982, PCMag has tested and rated thousands of products to help you make better buying decisions. See how we test. (Opens in a new window)

    troubleshoot, connection, refused, black, screen

    Once upon a time you could install RealVNC Server on a computer and connect to it another computer using the IP address, all without signing up for any kind of account. That’s not true anymore. At this point the RealVNC Server only works if you have a VNC Connect account.

    If you’d prefer a direct, IP-based connection, I recommend looking into TightVNC (Opens in a new window) for Windows devices. It’s an open-source application based on the same VNC protocol as RealVNC. Linux and macOS users should look into the built-in servers offered by their operating systems, which can be found in the system settings. Windows has a built-in option too. You can even use RealVNC Viewer to connect to such devices, without a VNC Connect account, over your local network.

    How Much Does VNC Connect Cost?

    VNC Connect offers a free version for personal use limited to five remote computers for up to three users. This free version is a little hard to find—it’s not mentioned on the pricing page—but you can sign up here (Opens in a new window). Most remote access software doesn’t offer a free version, though TeamViewer does, and it’s our Editors’ Choice product for personal use. In fact, TeamViewer offers all the features of its paid product to personal home users for free, which is even more generous.

    VNC Connect’s paid offerings start at 40.68 per year per device you want to connect. That price is high compared with RemotePC, our Editors’ Choice pick for businesses, which can connect with one computer for 15 per year and 10 computers for 60 per year. RemotePC also performed better than VNC Connect in our tests. TeamViewer’s paid plans start at 414 per year, which sounds expensive until you realize that plan allows for managing up to 200 devices, while VNC Connect is priced per device. VNC Connect could work out to be cheaper if you’re only connecting to a couple of devices, but it ends up being considerably more expensive as soon as you’re connecting to a dozen or more.

    VNC Connect also offers an Instant Support feature for quickly connecting with a customer’s device. Plans start at 203.88 per technician per year. TeamViewer and RemotePC do not charge separately for this feature, which makes those services seem more affordable by comparison.

    Still, VNC Connect is priced competitively, particularly for small businesses that only connect to a few devices. VNC Connect makes less economic sense the more features you need, however.

    What Operating Systems Does VNC Connect Work With?

    You need two pieces of software to use VNC Connect: the RealVNC Server, which you install on the computers you want to access, and the RealVNC Viewer, which you install on the devices from which you want to access other computers. The server works on Windows (7 and later), macOS (10.10 Yosemite and later), Linux (Ubuntu 16.04 and later, for reference). The Viewer is compatible with all the same versions of Windows, macOS, Linux, but also iOS (9 and later) and iPadOS (13 and later), Android (6 Marshmallow and later).

    There’s one more version of RealVNC: a “disposable” version used for instant support, and it’s only compatible with Windows and macOS devices—Linux isn’t supported.

    Getting Started With VNC Connect

    To start using VNC Connect you need an account. You can sign up for a 14-day free trial or the free home version. Either way you do not need a credit or debit card number.

    After setting up an account you see instructions telling you to install the Real VNC Server on the computers you want to access remotely and the Real VNC Viewer on the devices you want to access the computers from. You then need to sign into your VNC Connect account on all devices.

    VNC Connect also offers an instant support feature—look for a button for starting a session right in the toolbar. This will give you a one-time code and instructions that a customer can use to allow you to take control of their computer.

    You can email the instructions and the code or read them out over the phone. Either way, it’s a quick process.

    Troubleshooting With VNC

    I installed RealVNC Server on a Windows 10 computer and installed RealVNC Viewer on a MacBook Pro, a Windows 11 laptop, and an iPad Mini. I tested the service by connecting over my local network and via my neighbor’s distant Wi-Fi connection. VNC Connect performs adequately, particularly if all you need to do is troubleshoot a problem or edit a few documents. For anything related to graphics or video, however, VNC Connect lags too much to be useful. Watching a video, which works great with the likes of TeamViewer and RemotePC, isn’t really possible over VNC Connect. The frame rate is simply too low. I also found remote audio to be occasionally garbled, though good enough for troubleshooting purposes.

    The macOS and Windows versions of RealVNC Viewer offer all the same features. A toolbar at the top of the screen, which hides automatically when not being used, is the only real user interface element. The result is a clean app that doesn’t get in your way, and that’s what you want in a tool mainly used for troubleshooting.

    You can control the mobile version of RealVNC Viewer using gestures, a full list of which are presented to you after you log in. Pinching and reverse pinching zooms in and out, tapping and dragging moves the mouse, and tapping once is a click. You also get a virtual keyboard, brought up using a toolbar on the top of the screen. It’s all a little clumsy, but usable once you get the hang of it.

    Transferring Files the Hard Way

    RealVNC does not offer any kind of dual-pane file-transfer service, meaning you can’t browse the file system of both devices at once; and there’s no click-and-drag file transfers like you get with GoToMyPC and Splashtop. You can, however, choose which folder you’d like to send files to and then choose which files to send. Transfers from the remote machine need to be started within the VNC window. Once again, it’s clumsy compared with most remote access software, but it does work.

    Text chat is offered, which at least allows for some communication with anyone sitting at the other device, but you don’t get built-in audio or video chat. Neither do you get a virtual whiteboard, meaning you can’t draw on the screen to show someone what’s going on. TeamViewer and RemotePC both have whiteboard tools.

    Connecting to a device with multiple monitors shows, by default, all monitors, though you can change this setting by pressing F8 and choosing to see a single display instead. RealVNC also makes recording any session easy—just press the Record button. Sessions are saved in the WebM format on the local device.

    There Are Better Choices for Remote Access

    VNC Connect is fine. It’s not the best-performing remote access software. It’s not the easiest such software to set up or use. It’s not the most affordable, and it’s not the most feature-rich. But it does work.

    Still, if you’re looking to use remote access software for home use, we recommend TeamViewer first, our Editors’ Choice winner for personal use. Our Editors’ Choice winner for business use is RemotePC, which performs better than VNC Connect while also being more affordable.
