L2TP VPN iPhone iPad Troubleshooting
The VPN Does Not Connect
Confirm that the server address, username, password, and pre-shared key are correct. Make sure there are no accidental spaces before or after any of the information.
Note: If you are connecting from a country with strict internet filtering, inspection, or VPN restrictions—such as China, Iran, Russia, Cuba, or Turkmenistan—your internet provider or local network may block or interfere with L2TP/IPsec VPN connections. In these locations, the VPN may fail to connect even when all settings are correct.
The Shared Secret Is Incorrect
The Secret field must contain the IPsec pre-shared key provided with your account. It is different from your account password.

Disconnect the VPN, switch between Wi-Fi and mobile data, and reconnect. Also confirm that Send All Traffic is enabled.
