This may be a two-parter, but:

Swapped out my singular Cache NVMe drive to larger one (512->1TB) following these instructions: https://forums.unraid.net/topic/46802-faq-for-unraid-v6/#comment-511923
 

I moved everything to one of my Pools, which is Encrypted and that may be my problem... but...

Unfortunately when I got to this part:

For v6.12.0 or newer: Click on Shares and change the mover action to move from array to pool for all shares that you want moved back to cache

On the Main page click "Move Now"

When the mover finishes re-enable Docker and VMs

The mover moved.... nothing. I reversed things to go from my device pool->cache, and it just blinks at me.  I am fairly certain the drives were mounted and unlocked, but at this point I'm unsure because it was last night and I wanted to sleep on my frustration.

I thought perhaps a server upgrade would help solve the problem, but I ran the upgrade to 7.1.2 and now I can't access the GUI at all (before, I could)

The error messages I got: 
sed: can't read /etc/nginx/conf.d/locations.conf  No such file or directory
nginx: [emerg] open() "/etc/nginx/conf.d/servers.conf" failed (2: no such file or directory) in /etc/nginx/nginx.conf:163

When I check on the command line, both of those files DO exist at those paths, and have -rw-r--r-- permissions

I'm sure I can figure out the Cache drive issue, but my primary focus is getting the GUI back. I attached the logs. Thank you in adavnce

Nginx is failing to start, but don't see why:

 

May 15 07:40:09 zemuria rc.nginx: Nginx server daemon...  Failed.

 

Try removing the certificate from the flash drive, since that's been an issue before, if that doesn't help, you can try redoing the flash drive, backup the current one first and then recreate it using the USB tool 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 (\config\plugins\dockerMan\templates-user), 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.    

Fair enough - thanks for looking. I'll just rebuild it. So far, so good, on the effort here
