further to my earlier response, if you do notice a lockout please could you try to get the output from this request saved into a text file
http://127.0.0.1:32400/connections?X-Plex-Token=xxxxxxxxxxxxxx
and send to me by private message - and of course collect the logs as well with debug logging enabled beforehand
The token string can be found in Preferences.xml or following the steps outlined here https://support.plex.tv/articles/204059436-finding-an-authentication-token-x-plex-token/
From what i have seen the lockouts are transient and not permanent - of course the /connections request needs to be done when http://127.0.0.1:32400/web hangs and you know the server is actually running
