I am having similar problems.
First, I cannot connect to shares from windows. After unraid reboot, before array mounted, I can see my unraid server in [Network], and I can see there is no share in it. After array mounted, I can no longer connected to unraid server. I can ping its IP, just cannot map a network drive or access through windows.
Then I started changing settings for SMB, but every time I stop array, it gets stuck at " Array Stopping•Retry unmounting disk share(s)...".
I boot into safe mode, everything seems the same. Attached is diagnostics under safe mode.
Thanks in advance.
