I'll try the fix.
I have had this issue for weeks now. This only happens on FoxSports app. Does not happen on other live TV apps such as ESPN and USA Network.
I have a Roku TV, provider is Verizon FIOS.
Even this morning, I was watching the world cup and I get this error every 10-20 minutes. Happens every time. It is annoying to go back and restart the live game, as you miss 2-3 minutes every time.
So that is my situation as described above with TCL Roku TV.
I recently purchase a Roku Streaming Stick 4k. When I plug this into to the Roku TV HDMI port, I can watch on this Roku streaming device without the issue, but the issue still persists on ROKU TV.
I don't know what to make of it. So my Roku in Roku configuration is working. So for World Cup matches I use the Rokustick and for all other streaming I use the Roku TV.
