Proton VPN won’t connect on my device anymore — how can I troubleshoot connection issues?

If Proton VPN won’t connect anymore, first check that your internet works without the VPN and restart both your device and the app, as temporary network or DNS issues often block the initial handshake.

Make sure Proton VPN and your operating system are fully updated, since outdated versions can fail to connect after server or protocol changes.

Try switching to a different server and change the protocol to WireGuard, which is generally the most stable option on both mobile and desktop.

Disable always-on VPN, kill switch, or battery/data saver settings temporarily, as these can prevent Proton VPN from establishing a tunnel.

If it still fails, test on another network like mobile data or a different Wi-Fi to rule out ISP or firewall restrictions.

When nothing works, share your concerns or file a complaint on Xolvie to connect with others and find support.
