Goto the Setting gear on the top right and select "Users". Next you want to click on the user account that you are using and hit the edit icon (Looks like a pen).
On "Device Limit" input -1
-1 is unlimited
Hit check mark on bottom of that window to save. You should be fine now.

Unauthorized means that you are not logged in or timed out for some reason.
My bad. looked like an error I had before after upgrading. many of my users had 0 for Device limit. I will be sure the errors match better next time. Thank you
I just installed traccar server, and I'm trying to add device at web page.
I'm getting http 401 Unauthorized - WebApplicationException( SecurityRequestFilter:108 <...)
I was logged with admin user.
