I think I have the same issue.
My servers was still running with an screen attached and I got no output. the web interface of unraid wasnt reachable and every webpage I am hosting had the same issue.
I had this problem before and also wasnt able to find the solution to it.
(While typing My screen turned black and i wasnt able to get it back, solution was replugging the usb dongle and turning the keyboard (logitech k400+) off/on after this typing made the screen come back. Mayby this was also the problem I had before will try this out next time it happens.)
I wil list my server specs mayby someone in the future will find this topic and something simulair:

Something weird I had before this problem is: I was not able to open shares with \\192.168.0.5\share but i was able to load \\unraid.local\share, after one reboot of the unraid server i was able to open the share with both option again.
Hope someone finds this intressting
