Like others, I've been unable to access my WebUI from other computers ever since I upgraded to 7.3.1. When attempting to access the WebUI, I get a 404 error with nginx below the error.

Aside from the WebUI problem, my services appear to be functioning correctly. That said, my system has had two unprompted unclean reboots ever since the upgrade - it's difficult to diagnose since I don't normally interact directly with the unRaid GUI without going through WebUI plus the system is almost 10 years old (so I won't be surprised that I'm seeing early signs of hardware failure).

Attached is my latest diagnostics file. Please help me resolve the WebUI issue.

Don't see any obvious issues, both the array and nginx are started, did you try in safe mode to rule out a plugin issue?

Also, are you trying to access the server by name or IP? If the former try the IP http://192.168.1.25

OK, that is weird. It does access via IP! I've never had an issue accessing it via the name before.

To continue the weirdness: I've been unable to access the WebUI via hostname for 3 days since I performed the upgrade (across multiple reboots both planned and unplanned). After I accessed the WebUI via IP, the hostname allowed access to the WebUI again.
