This material explains lawful network security and configuration scenarios. Follow the rules that apply in your location.
Check the internet without the VPN
Disconnect the tunnel and open several sites. A VPN cannot replace a failed underlying connection. Restart Wi-Fi or mobile data before continuing.
Check the device date and time as well. A large clock error may interfere with secure sessions and certificate validation.
Check the subscription and key
Open the Telegram bot and confirm that the plan is active, the device is within the limit and the key has not been replaced. If the profile changed recently, remove the old entry and import the current one.
Never post the key in a public support channel. Account identity, error time and profile name are enough for an initial check.
Remove app conflicts
Pause another VPN, system proxy, DNS filter or blocker that uses the VPN interface. Phones allow one system tunnel at a time, and Windows routes may conflict even after an old client window closes.
Restart the app and, if needed, the device. This clears a stuck virtual adapter and stale DNS state.
Compare protocol and network
If AmneziaWG fails, test VLESS + Reality, or the other way around. Then compare Wi-Fi with mobile data. The result shows whether the issue follows a profile, network or device.
For low speed, try a different available route or time window. A single speed test can reflect temporary load anywhere along the path.
What support needs
Provide the device model, operating system, client version, protocol, network type, exact time and error text. A status screenshot helps after private keys and personal details are hidden.
Frequently asked questions
The VPN connects but there is no internet. What now?
Reconnect, pause conflicting DNS or VPN apps, test the other protocol and compare on another network.
Why is the VPN slower in the evening?
Home, provider and route load often rises in the evening. Compare with and without the VPN, then repeat on a different network.
Should I reinstall the app?
Usually not at first. Refresh the profile and restart the client and device. Reinstall only when the client or virtual adapter appears damaged.
