Common troubleshooting steps universal

Restart everything: device, router, modem.
Test on another network: mobile data or a friend’s Wi-Fi to see if the issue is local to your network.
Check Proton VPN server status: protonvpn.com/status or status.protonvpn.com to see if outages exist.
Switch servers or protocols: try a different server location or protocol OpenVPN, IKEv2, WireGuard.
Disable IPv6 temporarily: some networks misbehave with IPv6; disable it in network settings, then retry.
Temporarily disable firewall/antivirus to test. If VPN opens, add exceptions back with proper rules.
Reinstall the app if persistent issues persist across steps.

Network and server considerations

DNS leaks or blocks can prevent VPN from opening properly. Use trusted DNS providers Cloudflare 1.1.1.1, Google 8.8.8.8 and ensure your DNS settings aren’t forcing non-encrypted traffic.
Router VPN issues: if you’re using Proton VPN at the router level, verify firmware compatibility and router DNS settings. Some consumer routers require specific VPN passthrough support.
Proxy and VPN conflicts: If you’re behind a corporate proxy, you may need to configure Proton VPN to work with proxy settings or bypass the proxy for VPN connections.
Bandwidth and congestion: during peak times, connections may be slower or less stable, leading to startup problems. Reconnecting to a less congested server might help.

Security and privacy considerations

VPN startup problems can sometimes indicate security software blocking connections. Review security software logs for blocked connections and add Proton VPN as an allowed program if necessary.
If you’ve recently changed your subscription or account details, confirm your Proton VPN account status at your account page to ensure your device is authorized.
