Platform-specific tips: Windows, macOS, Android, iOS
Windows
- Run as administrator: right-click the Proton VPN icon and choose “Run as administrator”
- Change protocol: in Settings > Protocol, try WireGuard UDP if you’re on UDP or switch to TCP if UDP is blocked
- Check Windows Firewall: allow Proton VPN through firewall rules; create an inbound/outbound rule if needed
- Disable third-party VPNs or proxies that could conflict
- Ensure DNS leak protection is configured appropriately in the app settings
MacOS
- Check Network Preferences: ensure Proton VPN is allowed to create a VPN interface
- Try a different server and protocol
- Reset network settings if you’ve recently updated macOS or installed new security software
- Ensure the app has all necessary permissions under System Preferences > Security & Privacy
Android

- Try a different server and protocol; some carriers block UDP
- Disable battery saver or optimize battery settings for Proton VPN
- Clear cache for the Proton VPN app if you’re on older Android versions

- Remove and re-add the VPN profile if needed
- Ensure the app has permission to use VPN in Settings
- If you’re behind a corporate network, test on a cellular connection to verify it’s not a network block
Network and firewall considerations: why your network could block Proton VPN
- Some public or corporate networks block VPN traffic, especially on standard ports
- Firewall rules or ISP-level blocking can interfere with specific protocols
- If using a home router, ensure VPN passthrough is enabled for the relevant protocol WireGuard or OpenVPN
- Check for double NAT situations; if you’re behind two routers, VPN performance can degrade or fail to connect
- QoS or bandwidth limiting can disrupt VPN handshake; try disabling QoS temporarily
Protocols, kill switch, and split tunneling: tune for reliability
- Protocol choice matters: WireGuard recommended for speed and reliability vs OpenVPN older but widely compatible vs IKEv2
- If a protocol fails to connect, switch to another protocol and retry
- Kill switch: enable it to prevent traffic leaks if you temporarily lose VPN connection; ensure it’s correctly configured
- Split tunneling: if you only need certain apps to use the VPN, use split tunneling; disable it temporarily if you’re testing a connection
- DNS settings: use Proton VPN DNS or set a custom DNS like 1.1.1.1 to avoid DNS leaks that can affect connection stability
Common error messages and what they mean
- “Connection failed” or “Unable to connect to server”: server or protocol may be blocked; try different server or protocol
- “Authentication failed”: login issue; refresh token or re-login
- “No internet connection”: your device can’t reach the internet; fix your base connection first
- “DNS leak detected” or “DNS not secure”: switch DNS to Proton DNS in settings
- “Kill switch blocked”: app doesn’t have permission to enforce the kill switch; check device permissions
Diagnostics and deeper troubleshooting
- Check Proton VPN server status: some servers go down for maintenance
- Test on a different device or network: isolates device vs network problem
- Use a wired connection if possible to reduce wireless interference
- Review event logs in Proton VPN for error codes and timestamps; search those codes in Proton VPN support forums
- Flush DNS cache:
- Windows: ipconfig /flushdns
- macOS: sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder
- Android/iOS: toggle Airplane mode on/off
- Check for VPN conflicts: uninstall other VPN apps or security apps that create VPN-like adapters
- Update network drivers and OS: ensure you’re on the latest versions
- Disable IPv6: some networks don’t handle IPv6 well with VPNs; turn it off temporarily
