Unable to log in (regular or AdminCP)

Maybe you have NGINX configure wrong so everyone's IP's is the same?

It actually appears that I had the wrong password.

I executed the following:

SELECT password FROM user WHERE userid=MyID;

I got the password hash, then used this to change it:

UPDATE user SET password=MD5(concat(MD5('MyPassword'),user.salt)) WHERE userid=MyID;

I then checked the password hash again, and it was different.

I don't remember changing it, but everything else seems okay. I'm still waiting on response from my users to make sure they can all log in okay.
