When my TCL/Roku tv is off and is turned back on, and I try to access an app (YouTube tv, Netflix, Hulu etc) I will get an error message “internet connection error” or there will the app won’t start. In order to fix it, I have to go to the roku home, check internet connection then it will start working again. I have an orbi router/satellite nearby so it not the router. I have other roku/tcl TVs without any issues. I have also changed the 2.4ghz channel on the router which has helped some. I’ve done master resets on the tv and internet connection but continue to have this problem sporadically.
