Value of 2 is no longer in use
Ref: Plex Media Server - #482 by drzoidberg33
Values used now are:
0 : Required
1: Preferred
And after changing, a restart of PMS is needed
In an SSH console, type:
$(getcfg -f /etc/config/qpkg.conf PlexMediaServer Install_path)/plex.sh restart
Or restart from QTS AppCenter
When said, are you sure that’s the problem, since mentioned clients should support a secure connection
