SG-2220 - 2.2.5 - Dashboard not reachable, every other GUI page is working fine.

[filnko]

I got 2 SG-2220 just a few days ago and restored my previous configs there.

After updating one of them from 2.2.4 to 2.2.5 the dashboard is not reachable though EVERY other webgui page is.
Already checked the system logs, nothing strange there.

Any recommendations?
