This article describes how to resolve an issue wherein the Sophos Connect GUI display "Service unavailable".

What to do

The following screenshot shows that Sophos Connect GUI displays "Service unavailable".

Cause of this issue: When a tunnel disconnect is initiated, the strongSwan IPsec daemon gets stuck in an infinite loop. This will result in the GUI not getting a response for disconnect and ultimately timeout and show the error as "Service unavailable".

Workaround for Mac: Refer to the Sophos Connect Application online help.

Workaround for Windows: Refer to the steps mentioned below:

  1. Run cmd as an Administrator then run the following two commands.
  2. net stop scvpn
  3. net start scvpn
  4. Open Sophos Connect, verify and check that the "Service unavailable" error is now resolved.

  • Hello,

    A t the moment there’s no link to download the installer directly. If you have an open case, you can ask the Engineer assigned to the case, to provide you with the file.

    If you’re being affected by this but don't have a case you can send me a PM and I can share the installer.

    If the installer doesn't fix the issue, a case needs to be open, if you have an open case, it needs to be escalated or if the case is with GES provide feedback in the case.
