Ooooh boy, I don't know what I did. 

I had Tailscale plugin running before, but I wanted to start fresh and get some things working.  I had advertised subnet routes before, and when doing the command tailscale up --advertise-routes=192.168.50.0/24, I had a feeling that maybe there were old settings in there that were competing and maybe needed to be cleared out.  I tried tailscale down, and removing/readding the plugin.  And somewhere in the process, I found that I couldn't get my docker containers to open by their IP address.  In the process of trying a few things, I lost my ability to remote into Unraid at all.

I restarted the server in GUI mode so I could see what I was doing.  I was able to restore my ability to remote into the server via the IP address login page, so that's progress.  But still no access via my custom docker network (every container has it's own IP address in my regular network scheme, so like 192.168.50.100 is Unraid, .101 might be Sonarr, .102 Radarr, etc.  

I figured that meant my whole system is down, but on a whim tried emby.myserver.com and PRESTO, the thing is working that way.  So, being a Friday, and with a new kitten on the way tomorrow and plans tonight, I figured okay, stop touching things right now, leave it alone, the front end is working even if I torched the backend. lol

If someone could help me figure out what I did, or better yet what to undo, I'd be greatful.  I'm not really familiar with the command line, so I shouldn't have randomly tried various tailscale commands.  But when in a hole, stop digging lol.  So I'm not trying more until I have a better idea what to do.

Attached are my diagnostics and my deepest thanks

Try rebooting in safe mode and retest.

Thank you, I'll try that sometime early next week (server is heavily used on weekends) and get back to the forum with those results!

Tried safe mode, and no dice:  I can get to services I have that use a domain (emby.mydomain.com, requests.mydomain.com) but I still cannot get to anything by internal IP.  So using safe mode hasn't changed anything for me.

In that case I would recommend redoing the flash drive, backup the current one first and then redo it and just restore the bare minimum, like the key, super.dat and the pools folder for the assignments, also copy the docker user templates folder, if all works you can then reconfigure the server or try restoring a few config files at a time from the backup to see if you can find the culprit.

I'm not sure I understand, so would I be starting with a brand new install of Unraid on my drive and then bring these items over?  Also I had to get "permission" to use this drive, as I was out of UIDs, will I run into that again? 

I notice there's been no opening of the .zip file I have with diagnostics, is there some chance a less chaotic fix might be discovered in there?  I'm not super keen on the idea of redoing my whole boot drive.  I'm on chemo this week and I'd like to keep further distasters to a minimum while I recover :).

You can use the same flash drive.

 

Before that you can also try to recreate the docker image, in case it's an issue with custom networks:

 

https://docs.unraid.net/unraid-os/manual/docker-management/#re-create-the-docker-image-file
Then:
https://docs.unraid.net/unraid-os/manual/docker-management/#re-installing-docker-applications
Also see below if you have any custom docker networks:
https://docs.unraid.net/unraid-os/manual/docker-management/#docker-custom-networks

Turns out there was nothing wrong with my Unraid installation at all, all of the points of failure were on my Desktop.  I found I could access everything via my phone.  So I tried from my desktop again on another browser, but it still failed.  Then I removed the Tailscale software running on my desktop and it worked again.
