Yesterday I was transferring some files from an external hdd (in a usb 3.0 dock) to the array.
I mounted the ext hdd via the unassigned devices plug-in.
I was performing a verbose rsync, and after about half the directory was transferred I/O errors popped up.
The external drive had become unmounted. I remounted in unassigned devices, and restarted the rsync.
Eventually I noticed the same errors again, but this time I could not remount the hdd.
Unlike the first involuntary unmount, I could no longer see unassigned devices settings in the web ui.
Eventually the entire web ui stopped working, and gave me 500 errors.
I could ssh to the server, and all my docker containers were still working.
I tried a few things- restarting nginx, etc, per suggestions in the forum, but nothing brought the web ui back.
FYI: I tried two web browsers from my laptop (brave and firefox.) Neither worked, nor did accessing from a tablet and phone (chrome and brave.)
So finally I ran "diagnostics," and rebooted from the cli
#reboot
After restart, I still get 500 errors attempting to access the web ui.
I can access via ssh, and the docker containers all work. (Though SMB does not for some reason.)
Here is what I expect is the significant portion of the diagnostics syslog:

I deleated /boot/config/ssl per some suggestion in this forum, and rebooted again, and I still have the same problem.
Any suggestions? I am medium-level tech savvy fwiw.
