Quick diagnostic flow

Confirm you actually have internet outside Proton VPN. Open a browser and visit a page without the VPN on.
If you’re seeing “no internet access” only when Proton VPN is on, the issue is likely VPN-related, not your entire network.
Check VPN server status and try a different server or protocol.
Review app permissions and firewall rules.
If nothing works, reset the app or reinstall.

Check your network and device basics

Internet connection sanity check: Make sure your device isn’t offline. Try a different app or another device on the same network.
Reboot basics: A simple reboot of your device can clear stuck network states.
Network hardware: If you’re on Wi‑Fi, restart your router. If you’re on mobile data, toggle airplane mode on/off.
Date and time: Ensure your device clock is correct. VPN apps rely on certificates and time-based keys.
DNS sanity: Try using a public DNS like Google DNS 8.8.8.8, 8.8.4.4 or Cloudflare DNS 1.1.1.1. This can help resolve DNS leaks or delays when the VPN is active.
Bandwidth tests: If you’re on a constrained network cafés, airports, schools, some networks block VPN traffic or throttle it. Try a different network to verify.

Proton VPN app troubleshooting by platform
Windows

Update Proton VPN: Ensure you’re on the latest version. Go to Proton VPN > Check for updates.
Run as administrator: Right-click the Proton VPN icon and select “Run as administrator” to ensure all network hooks load correctly.
Change protocol: In settings, try UDP vs TCP, or switch to WireGuard protocol if you’re on OpenVPN. Some networks block a specific protocol.
Kill switch and DNS leak: If the kill switch is on, try turning it off temporarily to test connectivity. Ensure DNS leak protection is enabled to prevent leaks.
Disable IPv6: Some networks and VPNs have issues with IPv6. In Windows, disable IPv6 for your adapter to see if that helps.
Firewall rules: Ensure Proton VPN isn’t blocked by Windows Defender Firewall. Add an exception if needed.
Flush DNS: Open Command Prompt as administrator and run:
- ipconfig /flushdns
Network reset: If problems persist, use Windows’ Network Reset option to rebuild network stacks, then reinstall Proton VPN.

MacOS

Update and reinstall: Make sure Proton VPN is up-to-date. If needed, reinstall.
Protocol and server switch: Try switching servers and protocols in the app. Some macOS networks prefer WireGuard.
Gatekeeper and permissions: Ensure Proton VPN has the necessary permissions in Security & Privacy > Privacy.
DNS settings: Clear DNS caches with sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder.
Network location: Switch to a different network location in System Preferences > Network to ensure clean network state.
Firewall: Check macOS Firewall settings to ensure Proton VPN isn’t blocked.

Update app: Make sure Proton VPN is updated from Google Play.
VPN permission: Confirm the app has the required system permissions.
Protocol switch: Toggle between WireGuard and OpenVPN within the app.
Battery saver: Turn off battery optimization for Proton VPN, as aggressive optimizations can block VPN traffic.
Data saver and background restrictions: Ensure Proton VPN isn’t restricted from running in the background.
Reinstall: If issues persist, uninstall and reinstall the app.

IOS

iOS permissions: Ensure Proton VPN has VPN and network configuration permissions.
Protocol and server: Try switching servers or protocol within the app.
VPN configuration reset: Remove the VPN profile and re-add it via the Proton VPN app.
iOS network reset: In extreme cases, reset network settings Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings. Note: This clears saved networks.

Protocols, ports, and firewall considerations

Protocols: WireGuard is fast and usually reliable; OpenVPN is widely compatible but can be slower on some networks. If one protocol fails, switch to the other.
Ports: Proton VPN generally uses standard ports. If your network blocks VPN ports, switching protocols can help.
Firewalls and security appliances: Corporate networks or public Wi‑Fi hotspots often block VPN traffic. If possible, try a different network or ask the network admin about VPN access.
DNS and leaks: Use the built-in DNS leak protection and a reliable DNS configuration to prevent leaks while connected.

DNS, split tunneling, and kill switch tips

DNS leak protection: Always enable DNS leak protection to avoid exposing DNS lookups to your ISP.
Split tunneling: If you only need VPN protection for certain apps, use split tunneling. If you’re troubleshooting, disable split tunneling to ensure all traffic goes through VPN.
Kill switch: Use the kill switch to prevent traffic leakage if the VPN disconnects. Test it by turning off the VPN and confirming there’s no data leakage.

Router and device-level fixes

Reboot router and modem: A simple reboot can fix many router-level issues that affect VPNs.
VPN on router: If Proton VPN supports router-level VPNs, consider configuring it on the router for all devices. This can avoid device-by-device issues, but it’s more complex.
ISP blocks: Some ISPs throttle or block VPN traffic on certain plans. If you suspect this, try a different router or consult ISP support.
DNS on router: Set the router to use a trusted DNS 8.8.8.8, 1.1.1.1 to improve resolution reliability while VPN is active.

Security and permissions Best vpn for ubiquiti your guide to secure network connections

App permissions: Ensure Proton VPN has the minimum required permissions to function properly on your device.
Privacy settings: Confirm that privacy settings aren’t blocking VPN traffic or preventing the app from establishing a tunnel.
Certificates and time sync: Make sure system time is accurate to avoid certificate validation problems.
Malware and antivirus: Some security tools can block VPN traffic. Temporarily disable or configure exceptions for Proton VPN to test.

When to consider alternatives or a backup VPN

If Proton VPN consistently fails across multiple devices on the same network, a broader issue might exist router misconfiguration, ISP blocks, or account problems.
NordVPN as a backup option can provide a solid alternative with similar features kill switch, DNS protection, split tunneling. Quick link: https://go.nordvpn.net/aff_c?offer_id=15&aff_id=132441&aff_sub=0401
