XGS4500 (SFOS 20.0.2 MR-2-Build378) after Firmware update from 20GA to MR2 stays dead

Hello Sophos Community,

we just updated two XGS4500 (in HA) to 20 MR2 and now the SSLVPN stays dead:

After checking the admin interfance I logged into the shell:

I used the command: service sslvpn:restart -ds nosync

503 Service Failed


We don't use SSLVPN (for now) but still we would like to know what we can do to get this service up again and running.

Thanks for your help

  • Hello,

    Thank you for contacting Sophos Community.

    Could you please share us the sslvpn.log while starting the service?

    You can collect using below:

    tail -f /log/sslvpn.log

    So I assume its due to an inactive sslvpn configuration right?
    If I delete it or disable the service then it should fine I guess
