Sophos XGS Site-To-Site SSL VPN will not auto connect after reboot

Hi Mook Sin Siew , can you share the sslvpn logs from both client and server sites ? Did you check that sslvpn process(es) were running on the client site XGS (ps|grep sslvpn) ?

Hi, from the log, 

sometime around 16:00, there was a power disruption and then power restored at  17:30.  We manually on/off the site to site SSL VPN, and that is at around 17:53 recorded above.

For Site-To-Site SSL VPN, we can't find anything on  Auto-Connect Settings. Can confirm?

Hi Mook Sin Siew ,

As far as I know there no settings available for auto-connect to enable to disable.

Since when you starting facing issue with SSL site to site ? it was working earlier ? Share the current firmware version of the firewalls

I would suggest IPSec site-to-site instead of SSLVPN site-to-site
