Token is not working

Server Version#:
Player Version#:
<If providing server logs please do NOT turn on verbose logging, only debug logging should be enabled>

Server 2016

Player is most current

I have uninstalled and reinstalled plex. It will open up first time then any time I try to use it I get a 401 error/token done some research and says I have to reclaim the serve. Not sure if this is correct. Every time I click on icon have 401 error, search for the app and only log files are found. Not sure why this token thing is a issue these days and not sure how to fix it. I did see a post about a program that fixes this issue but the link is dead. Any help would be great.

Can we please get a copy of your server logs?
