Server Version#:1.20.3.3437
Player Version#:plex web
A few days ago plex web stopped working on my raspberrry pi 4 with chromium it displays a “oh no” screen, I tried on chromium fedora 32 x86 and it didn’t work, it fails with this message: s4032 (Manifiesto)
I’m haven’t checked if both are required to do the trick but I enabled hw accel in chromium and then changed the resolution of raspbian to 720p, when I changed the resolution plex started working.
