Check for operating system updates

Verify permissions and security software

Antivirus or firewall rules can block the VPN client. Temporarily disable active protection or add ProtonVPN as an exception.
On mobile, ensure ProtonVPN has the required permissions VPN, Network access, etc..

DNS and network configuration

Change DNS to a public DNS Google 8.8.8.8 / 8.8.4.4 or Cloudflare 1.1.1.1 in network settings and test ProtonVPN again.
Flush DNS cache:
- Windows: open Command Prompt as admin and run ipconfig /flushdns
- macOS: open Terminal and run sudo killall -HUP mDNSResponder

Some apps like other VPNs, proxies, or network monitoring tools can interfere with ProtonVPN. Disable or uninstall conflicting software temporarily to test.

Common error codes and quick fixes

Tip 3: Always test a basic non-VPN connection first; if your internet is flaky, fix that before trying to connect to ProtonVPN.
