Why Mozilla VPN sometimes breaks down
Mozilla VPN is built to be simple, but several factors can cause problems:
- Network conflicts: other VPNs, proxies, or security software can interfere.
- DNS misconfigurations: DNS leaks can reveal your real IP.
- Outdated app or OS: software updates often fix bugs and improve stability.
- Protocol and server choices: some servers or protocols work better in specific regions or networks.
- Device constraints: low RAM, background apps, or battery-saver modes can disrupt VPN connections.
- Firewall or antivirus: overly aggressive rules can block VPN traffic.
Quick-start checklist to fix most issues
- Restart everything: device, router, and Mozilla VPN app.
- Switch servers: try a different location to test connectivity.
- Check for updates: update Mozilla VPN, your OS, and any network drivers.
- Verify permissions: ensure the app has the required permissions on your device.
- Test with another protocol: if available, switch between WireGuard and other supported protocols.
- Disable conflicting apps: temporarily turn off other VPNs, proxies, or security suites.
- Review firewall rules: allow Mozilla VPN traffic through the firewall.
- Check DNS settings: use Mozilla VPN’s DNS or a trusted DNS provider; ensure no DNS leaks.
- Run a leak test: verify your real IP is not leaking.
- Contact support with data: gather logs, server names, and steps to reproduce.
