Solutions to ProtonVPN Android app issues

VPN Connection fails due to gateway_unreachable error

Symptom: Starting and logging in to the ProtonVPN Android app is successful, however, when connecting to a server, the connection fails and returns error “Unable to VPN: gateway_unreachable”.

Cause: Most common issue causing this error is that IPSec passthrough is not enabled in the router settings.

Solution:

  • At first, if possible, try connecting on a different network or try using mobile data and check if the issue persists – this will give you a better idea whether IPSec being disabled is the main issue.
  • If the issue persists, open your router settings via a web browser and enter the IP Address of your router (usually the IP address is 192.168.1.1, you can also check it on the device itself).
  • After logging in to your router, you will have to look for IPSec settings in the router menu. Each router has different settings, so the best practice is to either check your router manual or consult with an IT specialist.

VPN Connection fails due to authentication failure

Symptom: Starting and logging in to the ProtonVPN Android app is successful, however, when connecting to a server, the connection fails. The Android application logs indicate “Auth Fail”. You can access the logs if you click the hamburger Menu button, and click “Show log”.

Cause: Likely due to hitting the maximum number of connected devices and/or too many recent connections (attempts) that were not properly terminated.

Solution:

  • Make sure that you are not exceeding your connection limit. The simultaneous connections are different for each plan. With the free plan, you cannot have more than 1 connection at a time. Make sure that you do not have a device in the other room that is still connected. Check out our plans for more details about the different features.
  • Wait about 5 minutes, and retry connecting to a different server. Our servers periodically “clean up” old and inactive sessions. If you’ve had a connection that was not closed properly (think, wifi dropped, device crashed or similar), our infrastructure will detect and close such connections after a certain waiting period.
  • If you have a paid subscription, check whether all invoices are paid, otherwise you will be able to log in to the app, but you won’t be able to connect.

    I try to connect to the VPN and my phone won’t let me click on the “ok” button. Please help ASAP.

  2. ProtonVPN Team

    Hello. Please make sure you have no night mode apps like Twilight on at the moment as it draws over other applications preventing the clickable OK.

    I ended up on a page blocked by Vodafone Germany with “Wichtiger Hinweis. Dieses Portal ist aufgrund eines urheberrechtlichen Anspruchs vorläufig nicht verfügbar.”

    Since then I can’t connect to your VPNs anymore. What should I do? Connecting via my mobile connection is still working.

  4. ProtonVPN Team

    Hello Peter, please check if your network is configured with some of possible website filtering`s like OpenDNS or parental controls. If not, please let our customer support team know about this as its valuable information and could help other customers too. https://protonvpn.com/support-form

    Unable to establish VPN connection: gateway unreachable. I’m using a school WiFi connection

  6. ProtonVPN Team

    Hello Mossty, it could be that the network you are trying to connect on is restricted with the closed ports that our application uses. Please try this connection method and contact our customer support team: https://protonvpn.com/support-form https://protonvpn.com/support/android-vpn-setup/

    With a previous VPN, i had to change the server connection from UDP to TCP/secure/443. Is that a user setting you can add?

  8. ProtonVPN Team

    Hello. Android application of ours does not have a choice for that since it is running on a different protocol, that is IKEv2. Only OpenVPN has the option to switch from UDP/TCP.

    Used to have no problem, but now on my android, it won’t connect. Tells me I’ve exceeded the number of connections? I’m the sole user of my account. Is there some sort of thing such as closing all active sessions or something?

  14. ProtonVPN Team

    Hello Jon, please log out of your account within the application and log back in.

    Have a stable connection but have no idea how to do anything with it such as open a browser ? Do I just open my chrome app and it uses the VPN automatically?

  18. ProtonVPN Team

    Hello. When you have connected the VPN application, the internet traffic is all secured and your browser is using the VPN, so whenever you connect to the VPN server, you do not have to do anything else to be secured.

    No matter what server, my connection immediately disconnects as soon as I turn on WiFi. Worked before. I’ve tried several VPN and it’s the same. Also I’m told my email address is invalid which isn’t true.

  26. John

    My former VPN was evidentiary interfering with the connection. It’s okay now that I’ve uninstalled that.
    Thanks. I’m going to stay with you guys!
