• Temporarily disable firewall/antivirus: They can block VPN connections; re-enable after testing.

Common causes of “no internet” with Proton VPN

• Server or network congestion: A busy VPN server can look healthy but route traffic poorly.
• DNS leaks or misconfigurations: DNS requests leaking outside the tunnel can cause page loading failures.
• IPv6 leaks or misrouting: If IPv6 isn’t properly routed through the VPN, you may see no internet.
• Firewall or antivirus interference: Security software can block VPN traffic.
• Outdated app or OS: Older versions may have bugs or incompatibilities.
• Incorrect split tunneling settings: If critical traffic isn’t going through the VPN, you may feel offline.
• ISP throttling or network restrictions: Some networks block VPN protocols or traffic.
• DNS server issues: The DNS resolver your device uses could be slow or unreachable.

Step-by-step fixes: Windows, macOS, Android, iOS
Windows

• Quick connect: Open Proton VPN, click Quick Connect to auto-select a healthy server.
• Change protocol: In Settings, switch between WireGuard modern and OpenVPN legacy to see which works better.
• Flush DNS: Open Command Prompt as administrator and run ipconfig /flushdns, then renew: ipconfig /release and ipconfig /renew.
• Disable IPv6: Network & Internet settings > Change adapter options > right-click VPN connection > Properties > uncheck Internet Protocol Version 6 TCP/IPv6.
• Firewall rule tweak: Ensure Proton VPN is allowed through Windows Firewall Control Panel > System and Security > Windows Defender Firewall > Allow an app through firewall.
• Reinstall: Uninstall Proton VPN, reboot, reinstall the latest version.

MacOS

• Reconnect and switch servers: In Proton VPN, disconnect, then connect to a different server.
• DNS reset: System Preferences > Network > Advanced > DNS > remove any problematic DNS servers, re-add automatic or trusted DNS e.g., 1.1.1.1, 8.8.8.8.
• IPv6 off: System Preferences > Network > VPN > Advanced > TCP/IP > Configure IPv6: Off.
• Kill and relaunch: Quit Proton VPN, force quit related background processes, relaunch.

• Network settings reset last resort: Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings this resets Wi-Fi, VPN, and cellular settings.
• Ignore problematic profiles: If you have profiles or MDM, ensure Proton VPN is allowed.

Advanced fixes: DNS, IPv6, leaks, and split tunneling
DNS tweaks

• Use trusted DNS: In Proton VPN settings, enable DNS leak protection if available; set your device DNS to 1.1.1.1 or 9.9.9.9 as a test.
• Flush local DNS: As described earlier, flush DNS caches on your OS.
  IPv6 handling
• Disable IPv6 on devices and routers if you’re seeing IPv6 leaks or instability with VPN.
• If you must use IPv6, ensure Proton VPN supports IPv6 on the server you’re connected to; some servers route IPv6 only when the user opts in.
  Leaks and kill switch
• Verify there are no DNS, IPv6, or WebRTC leaks: Use tools like dnsleaktest.com, ipleak.net, or canyouseeme.org after connecting.
• Enable Kill Switch: Turn on Kill Switch to prevent leaks if the VPN drops.
  Split tunneling
• Use split tunneling to route only certain apps through VPN, others through normal internet. If essential apps fail, try routing more traffic through the VPN temporarily.
• Ensure critical apps your browser, streaming apps are set to use VPN if you rely on secure access.

Server and protocol considerations

• Protocol choice matters: WireGuard often provides faster and more reliable connections than OpenVPN on mobile networks. If you have issues, switch protocols.
• Choose nearby servers: Proximity reduces latency and improves reliability. If a nearby server is congested, pick a farther one with fewer users.
• Check server load: Proton VPN’s UI often shows server load; pick servers with lower load or try time-of-day alternatives.
• Proximity vs. content: For streaming or VOIP, a nearby server helps, but for accessing region-locked content, you may need a specific country server.

Networking tips to improve reliability

• Restart your router: A quick reboot can fix many home network hiccups and restore VPN performance.
• Use Ethernet when possible: A wired connection is more stable than Wi-Fi and reduces packet loss.
• Update firmware: Ensure your router’s firmware is current for compatibility with VPN traffic.
• Port considerations: Some networks block VPN ports; switching protocols or servers can help you bypass limited ports.
• Check for ISP throttling: If you suspect throttling, test with a different network mobile hotspot to confirm.

VPN vs. no VPN: when to use Proton VPN optimally

• Privacy and security: Use Proton VPN when you’re on public Wi-Fi or need encryption for sensitive tasks.
• Access to region-locked content: Use country-specific servers for streaming or accessing content not available in your region.
• Battery and device considerations: On mobile, keep an eye on battery usage; WireGuard tends to be lighter on battery than older protocols.
• Data caps and speed: If you’re on a capped plan or limited data, monitor VPN impact on speeds and adjust settings accordingly.

• Disable unnecessary plugins: In browsers or apps, disable unnecessary plugins that could leak data or conflict with VPN traffic.
• Review app permissions: Ensure Proton VPN has the necessary permissions on mobile devices to operate properly.
