I had an older Roku 4 and everything was working well. the Roku 4 died and I needed to replace it, I bought a Roku ultra 4800x. several server updates happened during the time I installed the new Roku and the time I actually tried to use it.

Nothing plays. no video from any source using the Plex app. it either gets stuck on 99% buffer or I just get a blank screen. I know this sounds like a Roku setting but for the life of me I can not figure out the problem. I have tried forcing the Roku to use 1080p and see if plex would work with that but that was also a no-go. Just to make sure it was not a server issue I am able to play movies on a PC and my phone streaming from the local server. if anyone else is having this problem or knows how to fix this I would be greatly appreciative.

Grabbed an older Roku from a different TV and plugged it into the one from above, it worked, it is definitely a Roku 4800 issue, I will contact Roku and see about it. again if someone has seen this problem please let me know.

I have a 4800 and it’s working for me (as well as my 46XX) - but that’s just anecdotal for reference.

Roku does some odd caching sometimes and unplugging it and replugging can clear oddities but if you swapped out devices I assume that already happened (it’s a more complete refresh than the menu option for “restart”). I don’t have to do that very often but occasionally it’s resolved other Roku oddities.

Might try reinstalling the Plex channel\app or even a factory reset on the device.

I’m not good at digging into the logs so if there’s anything there one of the more knowledgeable folks on that should be able to help too.

I did try another Roku, my phone, and a computer to make sure the server was actually working. I have had the server lock up on me before.

also uninstalled the app on Roku rebooted and then installed it again, still no go
