Troubleshooting
If something isn't working the way you expect, start here.
The app won't connect
Try switching to a different server, restart the Sentinel VPN app, and confirm your firewall isn't blocking outbound UDP traffic on port 51820.
Speeds feel slow
Pick a server geographically close to you, switch to the WireGuard protocol in Settings, and test a wired connection to rule out Wi-Fi issues.
Certain sites don't load
Try enabling Split Tunneling and excluding the affected app, or switch servers. Some networks intentionally block VPN endpoints.
Kill Switch keeps triggering
Kill Switch is doing its job — it drops your connection if the VPN tunnel fails. Update the app to the latest version and try a different server.
DNS leaks reported
Enable "Force Sentinel DNS" in Settings, disable IPv6 in your OS network settings, and re-run the leak test at browserleaks.com.
