Hey,

If an admin used /adminkey [wrongkey] he'd get the message "wrong key" or something along those lines.
if an admin used /adminkey [rightkey] the admin is instantly banned - reason "Cheating!"

Tried a few times with the same result.

Make sure you aren't in noclip, I can only player command you and if you have that blocked which you probably do you'll get banned.

I have this happening on my server as well, even without noclip.

Updated, you were in god mode.

I don't use godmode either. They are both set to false.

i got banned from my own server for trting to add admin was not in godmode or noclip

Me too

Is there a console command?

I was having the same issue so i did some testing.  Seems that ALL other plugins and godmode, etc. should be disabled/set to default before you use it.  It also instabanned me everytime i tried to bind it to a hotkey.  manually typing it everytime seems to work.
