I rolled back my server and now things work - so a server side issue.

Hi,
I also have this message on my mac with Firefox…
I tried restarting Plex Server on Synology, reopening Firefox but nothing helps.
Finally I tried Safari and it works very well
It must be an incompatibility with Firefox

Server Version 1.19.2.2737
client Version 4.22.2
