Last two days it says “plex is not reachable” check server sign in, connections, firewalls.
Note Netflix and every other app is working well so it cant be an internet connectivity issue.
First, I have already removed the Plex app, cleared the cache, power down the tv and restarted.
I reinstalled plex app on my TCL android (actually I do not think it’s an android tv, but it does have Opera store) software version v8-OMS08FP-LF1V062
In settings it says Plex for Opera TV 3.13.14
Opera TV store 0
The Opera app is no longer supported, and hasn’t been for a while. A cloud infrastructure change at the beginning of the month has now permanently broken your connectivity via the Plex app.
You will either need to purchase a new streaming device like a Roku, Amazon Fire Stick, Google ChromeCast, Apple TV, or upgrade your TV.
