SonicWall CSE Loss of Network Connectivity and Trouble Restarting the Connection

Loss of connectivity and trouble restarting the connection #

If end users are experiencing issues with Service Tunnel going down and not restarting in a timely manner.

Symptoms #

• End users cannot reconnect in under 10 minutes, for example.

Potential Root Cause #

• End users’ modems or ISPs pre-emptively determining that users’ connections were inactive, causing Service Tunnel sessions to time out.

Resolution Steps #

1. In the CSE desktop app, navigate from Settings > Preferences > Advanced Settings, and toggle on Enable Continuous Ping.

2. Set a time interval: This time interval setting determines the frequency with which the session is kept alive (e.g., set to Default).

Note: If you’re unsure of which time interval to set, consult with your org’s IT department.
