How Mozilla VPN works and what to check first
Mozilla VPN uses a secure network that routes your traffic through encrypted tunnels. If you’re seeing problems, often the culprit is something in this order:

- Try a different server location to rule out local server issues
- Check if your device’s firewall or antivirus blocks VPN traffic
- Enable or disable IPv6 as a test some networks prefer IPv4

- Change DNS settings to a public DNS 1.1.1.1 or 8.8.8.8 to see if DNS resolution improves
- Check for conflicting VPN software and uninstall it
macOS
