At some point on Windows using Edge browser, whenever I go to https://app.plex.tv to access my server, it says I’m not signed in. I click Sign In and am taking to the plex sign in page, click the Sign In butto and am sent back to my server. I get a popup saying my credentials have expired, but I can access everything. However the next time I open a browser and go back, it says I’m signed out again. All other players seem fine, its just plex’s web interface.

Tell your web browser to not delete the cookies of plex.tv when it’s closed.

@OttoKerner I’ve never set the browser to delete cookies from any sites on close.

It’s nowadays almost a default. Check the browser settings.
Do also check any 3rd-party tools which aim to “enhance privacy” by cleaning up Windows etc.
