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.

  • Hi Guys,

    I made a automation policy that uninstalls the client removes the C:\program files x86\Sophos dir and reinstall Sophos connect + import profile.

    Unfortunately this is the only solution in my case. 

    Btw: @ Offline 

    service is started in all cases. 

    I'm not sure but it seems this happens once per user. I'm in the middle of a deployment 70* users. I realy hope Sophos can comment on this insatiability issues. A lot of admins are now reluctant to deploy sophos connect on a large scale because it turns out to be unstable. Do not get me wrong. i am very positive about this product. I just hope it will turn more stable.
