Quick-start checklist

Reboot your device and your router if needed
Ensure Proton VPN is updated to the latest version
Try a different server location
Toggle VPN protocol OpenVPN UDP/TCP, WireGuard if available
Turn off the kill switch temporarily to test
Disable IPv6 on your device or router temporary test
Confirm your internet works without VPN
Check for app-specific firewall or antivirus interference
If you’re on mobile data, switch to Wi‑Fi or vice versa
If all else fails, reinstall Proton VPN and sign in again

Understanding the common causes

DNS issues: VPNs can misroute DNS requests, causing “no internet” even when connected.
Protocol mismatch: some networks block certain VPN protocols, leading to failed connections.
Kill switch misbehavior: a strict kill switch can block all traffic if the VPN tunnel isn’t up.
IPv6 leakage: IPv6 can bypass VPN when the tunnel is not handling it properly.
Firewall/antivirus interference: security software can block VPN connections.
Router-level blocks: ISP or router settings can block VPN traffic on certain ports.
App corruption or outdated app: stale installations can break connectivity.
Server-side issues: the Proton VPN server you’re on could be temporarily down.

DNS and IPv6:
- Disable IPv6 in VPN settings if supported; ensure DNS resolution works with the app.
Network restrictions:
- Some networks work, school block VPN traffic; test on a different network.
Reinstall:
- Delete and reinstall the app.

Linux

Update Proton VPN:
- Use your package manager or Proton VPN’s official instructions.
Protocol switch and DNS:
- Change protocol in config: wireguard or openvpn. Ensure DNS resolution is handled by VPN or local resolver with a test.
Kill switch:
- Ensure the kill switch is properly configured in the app or via command line.
Firewall:
- Check ufw/iptables rules that might block VPN ports.
Reinstall:
- Reinstall Proton VPN and re-authenticate.

DNS and leaks: how to test

DNS test steps:
- Connect to Proton VPN, then visit a DNS leak test site like dnsleaktest.com oriple test. Look for DNS requests outside the VPN tunnel your ISP’s servers or unexpected resolvers.
IPv6 test:
- Visit ipv6-test.com to see if IPv6 leaks occur when the VPN is active.
Kill switch verification:
- Disconnect VPN and try to access a geo-blocked site; you should not see your real IP if the kill switch is active.
WebRTC leak:
- Visit ipleak.net to check for WebRTC leaks; disable WebRTC in browser settings if needed.

Protocol and kill switch tips The Ultimate Guide Best VPN For Your UGREEN NAS In 2026: Best VPNs, Tips, And Setups

WireGuard is typically faster and more reliable on modern networks; switch away from TCP when possible if TCP is blocked.
If you’re on a flaky network, UDP may fail; TCP can be more reliable though slightly slower.
If you have a strict kill switch, consider temporarily using a trusted split-tunnel setup where only specific apps go through VPN if Proton VPN supports that.
Ensure you’re not forcing all traffic through VPN on a network that blocks VPN ports; in some cases, you may need to configure a fallback.

Router and network-wide fixes

If your router is the issue, install Proton VPN’s VPN on the router supported routers to secure all devices.
Ensure your router firmware is up to date.
Check port forwarding or firewall rules that might block VPN protocols especially UDP ports 500, 4500, 1194, 51820.
If your ISP blocks VPN, switch servers or use obfuscated servers if available.

Performance improvements and best practices

Pick a nearby server for lower latency; distance impacts speed.
Avoid peak times if you’re streaming; try servers optimized for streaming if you need that.
Use split tunneling to route only essential traffic through VPN to improve performance.
Regularly clear DNS cache on your device varies by OS after changes.
Keep your device time and date synchronized; certificate validation can fail if skewed.
Turn off other VPNs or proxy software that could conflict with Proton VPN.

Frequently Asked Questions

Table of Contents

What should I do first if Proton VPN says no internet?

First, reboot your device, update the Proton VPN app, try a different server, and test with a different protocol. Then check DNS and IPv6 settings. If it still fails, disable the kill switch for testing, and reinstall if needed. The Ultimate Guide Best VPNs For Your Sony Bravia TV In 2026

Why does Proton VPN sometimes show connected but not working?

This can be due to DNS leaks, IPv6 bypass, or a strict kill-switch. Test by disabling IPv6, switching protocols, and temporarily turning off the kill switch to see if traffic resumes.

How can I test for DNS leaks quickly?

Connect to Proton VPN, then visit dnsleaktest.com or dnsleak.com. If you see your home ISP’s DNS or non-VPN resolvers, you have a DNS leak. Change DNS settings or disable IPv6 to fix it.

Is WireGuard faster than OpenVPN with Proton VPN?

Yes, generally WireGuard provides faster speeds and lower latency, but it depends on your network. If you’re on a restrictive network, OpenVPN TCP can be more reliable.

Should I disable IPv6 to fix VPN issues?

Sometimes yes, as IPv6 can bypass the VPN tunnel. Disable IPv6 temporarily to test, and re-enable if you need IPv6 for other services.

How do I fix VPN on Windows if the kill switch blocks traffic?

Disable the kill switch temporarily to test. If the VPN works, there may be a misconfiguration; re-enable it after confirming the tunnel is up. If problems persist, reinstall. The Absolute Best VPNs for Your iPhone iPad in 2026 2: Top Picks, Real-World Tests, and Practical How-To’s

Can VPNs be blocked by my router or ISP?

Yes. Some routers or ISPs block VPN traffic on certain ports. Try different servers, different protocols, or install VPN on the router to bypass the issue.

What’s the best way to reinstall Proton VPN without losing data?

Uninstall Proton VPN, reboot, reinstall the latest version, and sign back in. Your subscription remains active; your settings may reset, so reconfigure as needed.

How can I prevent Proton VPN from breaking after a system update?

Keep Proton VPN updated, review network adapters, and test after major OS updates. Avoid skipping app updates; enable auto-update if possible.

Do VPNs affect streaming quality?

They can. If you’re watching HD/4K videos, choose servers optimized for streaming, reduce encryption overhead by picking a faster protocol, and minimize background tasks on your device.
