OctoPrint not working with VPN? Try this!

If your OctoPrint isn’t working with a VPN, thereby giving you a tough time getting your printing work done, these fixes will work for you.

But first, quickly do these checks and see if they solve the issue:

  • Check your internet connection. A quick speed test can help you detect if you have stable internet.
  • Restart your device and Wi-Fi router.

Not to worry, if you’ve done these and OctoPrint is still not working with VPN, try the below fixes:

  1. Change the VPN server

    Here’s how to do that:
    1. Open your VPN app.
    2. Disconnect from the server.

    3. Close the VPN app.
    4. Relaunch it and connect to another server.

    Some software and applications don’t function properly when connected to certain VPN servers.
    This is because those servers might not be optimized or configured to work for such apps and software.
    Therefore, it’s advised that you disconnect from that server and connect to another server in a different country.

  2. Check your VPN configuration

    If you use OctoPrint on a Raspberry Pi device, then this method is for you.
    Here’s how to check your Pi VPN configurations:
    1. SSH into your Raspberry Pi device.
    2. Run the following command: sudo nano /etc/openvpn/server.conf
    This will open the existing configuration in an editable text file.
    3. Verify that the configuration details such as the VPN server port number, IP address, and encryption settings are correct. If they’re not correct, you can change it in the text file.

    Alternatively, you can reinstall the app to ensure that you have the right configuration directly from your provider.
    Although it is a more advanced fix, it works if you can try it.
    On PC, you just have to open your VPN app and go to settings. From there, you can check and change the connection protocol, access ports, and other information.
    A faulty VPN configuration can cause the software to malfunction and experience a lot of connection issues.
    Be sure to check the details of your VPN configurations to see if they’re correct.
    If not, request new configuration settings from your VPN provider and try troubleshooting again.

  3. Contact your VPN provider

    The connection issue may be from your VPN as it may not have the features Raspberry Pi typically runs on.
    The good news is, many VPN providers on the market have a responsive support team either via email or 24/7 live chat team.
    So, contact them to rule out the possibility of the VPN not being compatible with the Raspberry Pi which powers OctoPrint.

  4. Contact the OctoPrint community

    While OctoPrint may not have a dedicated support team due to the open-source and crowdfunded nature of the service, you can ask for help from the community of fellow users.

    To do that:
    Simply go to OctoPrint.org and click the forum tab to go to the membership community.
    Browse through the existing topic asking for help with this problem of OctoPrint not working with VPN.
    Otherwise, sign up or log in to create a new topic to get help from the community.

  5. Change your VPN provider

    If after contacting your provider’s support team, you discover that the problem is due to the incompatibility of the VPN and the Raspberry Pi device, the sure fix is to change to another VPN provider.

    Also, if you keep trying to troubleshoot and Octoprint still isnt’ working with your VPN, then it’s probably time to give another provider a chance.
