Common causes of Proton VPN no internet access
DNS resolution problems
DNS issues are the number one culprit when VPNs fail to route traffic correctly. If your DNS isn’t resolving domain names while connected to Proton VPN, you’ll see websites fail to load even though you’re “connected.”
Protocol incompatibilities
Proton VPN supports multiple protocols OpenVPN, WireGuard, IKEv2. If your device or network blocks a chosen protocol, you’ll get connected but no traffic or very slow speeds.
IP leaks or IPv6 conflicts
Sometimes IPv6 or misconfigured IP routing can cause leaks or traffic to bypass the VPN or be blocked entirely by the service or network.
Firewall and security software
Antivirus or firewall suites sometimes block VPN ports or interfere with VPN tunnels, leading to failure to connect or dropped connections.
Outdated app or system
An old Proton VPN app or outdated OS can cause compatibility issues, resulting in connection problems or unstable VPN performance. Polymarket Withdrawal Woes Why Your VPN Might Be The Culprit And How To Fix It 2026
Network-level blocks
Some networks schools, workplaces, certain public Wi‑Fi block VPN traffic or require explicit whitelisting, which can prevent Proton VPN from establishing a tunnel.
Quick-start checklist 10-minute fix
- Ensure your base internet works without the VPN: try loading a page on your browser with the VPN off.
- Run Proton VPN as an administrator Windows or grant the necessary permissions macOS, Android, iOS.
- In Proton VPN, try a different server in a nearby country or region.
- Toggle the protocol: switch between OpenVPN UDP/TCP and WireGuard.
- Disable IPv6 on your device temporarily to see if it fixes the connection.
- Flush DNS: open Command Prompt Windows or Terminal macOS and run appropriate commands.
- Disable conflicting software temporarily: antivirus, firewall, or other VPNs.
- Reinstall Proton VPN if issues persist, and restore settings afterward.
- Check Proton VPN status to see if the problem is on their end.
Step-by-step troubleshooting guide
Step 1: Verify your base internet connection
