Sophos Connect GUI displays "Service Unavailable"

This error is more common on macOS. This error applies to IPsec VPN connections only.

Cause

When a tunnel disconnect is initiated, the strongSwan IPsec daemon gets stuck in an infinite loop. This results in the GUI not getting a response for disconnect, then time out and show the error as "Service Unavailable."

Remedy

  • On macOS, do as follows:
    1. Open the Activity Monitor and quit the Sophos Connect GUI process.
    2. Open the Terminal and run the following commands: sudo /bin/launchctl unload -w /Library/LaunchDaemons/com.sophos.connect.scvpn.plist then sudo /bin/launchctl load -w /Library/LaunchDaemons/com.sophos.connect.scvpn.plist
    3. Open Sophos Connect and check that the "Service unavailable" error is resolved.
  • On Windows, do as follows:
    1. Open cmd as administrator then run the following commands: net stop scvpn net start scvpn
    2. Open Sophos Connect and check that the "Service unavailable" error is now resolved.
