They recently deployed a fix (I dug into your thread)
wget https://downloads.plex.tv/plex-media-server-new/1.16.5.1554-1e5ff713d/debian/plexmediaserver_1.16.5.1554-1e5ff713d_amd64.deb?_ga=2.204785427.2008125745.1566530859-1649753701.1498437628
dpkg -i plexmediaserver_1.16.5.1554-1e5ff713d_amd64.deb
Will be testing this fix out tonight and will report back if it doesn’t. If I go quiet, consider it resolved
