The VPN channel may suddenly interrupt due to various reasons, here are some common ones:

  1. Network instability: The network connection between the VPN client and server may be unstable, resulting in the interruption of the VPN channel. For example, network congestion, signal interference or hardware failure can lead to network instability.

  2. VPN server issues: The VPN server may encounter problems, such as overload, maintenance or software failure, which may lead to the interruption of the VPN channel. In this case, you may need to contact the VPN service provider for assistance.

  3. Firewall or security software settings: The firewall or security software on the local computer or network may block the VPN connection, causing the VPN channel to be interrupted. You can check the firewall and security software settings to ensure that they allow VPN connections.

  4. VPN protocol or configuration issues: The VPN protocol or configuration may be incorrect, causing the VPN channel to fail. For example, the VPN client and server may use different VPN protocols, or there may be errors in the VPN configuration.

  5. Account or authentication issues: If you use a VPN account for authentication, account expiration, password changes or other issues may lead to VPN disconnection.
