Help & troubleshooting for channels on your Roku device, including adding/removing channels, logging in to, authenticating, or activating a channel, channel-specific playback issues, assistance contacting channel publishers to report issues, and adjusting channel-specific settings.
Over the past week i've had three YouTube videos on two separate Rokus stop playing around 30 seconds into the video with a message saying there was a network error and giving the option to exit youtube or cancel, other videos play fine. I didn't think to make a mental note of the first two videos unfortunately, but the third was this video. The Rokus are a Roku 3 4200X/Software Version 9.1.0/Build 4919-04 and a Roku TCL Tv 8111X/Software Version 9.1.0/Build 4917-48.
Dunno what you meant by "yesterday", Yorlin, but as an update I'd like to say that mine is not 100% fixed.
The error message came back so I went through the youtube menus and amoungst other things deleted the "watch history". This has made the message less frequent, and now when it does appear selecting "cancel" seems to mostly work as a way to carry on as normal.
