Ohhh! Ding ding, you solved it. There is a variable in the docker unraid yaml called "web password". And what looks like some sort of cronjob that makes sure it's set to what you have it as in unraid.
[i] Installing latest logrotate script...
[i] Existing logrotate file found. No changes made.
[i] Assigning password defined by Environment Variable
[✓] New password set
I just removed that key/value. That'll do it! Thanks.
I know Jacob hasn't been part of PiHole for years. I just like to joke with him any time I run into PiHole issues that he should fix it, since he wrote it 
Thanks for the help, this is considered solved.
