This is exactly my issue. Everything had been stable up until this point. My Plex became unresponsive on 7/8/22 at approximately 1600 and on 7/14/22 at 1943. Plex server still showed as running in the system tray, not accessible from web interface or client side.
@sa2000 , if it happens again how much time can elapse before I get the output from the Plex Token connections and process dump? The reason that I ask is that I am at work most of the day, and if the error happens again, I might be home hours later before I can run the necessary diagnostic steps. The only time that I am aware of a problem is whenever a family member tells me that they are unable to stream. This also means that the problem could have been present for quite a while before I am able to try to get the logs. Thanks for all of your help with this, it is really appreciated!
