I thought about it being the router because Roku channels stopped working on but TV's at the same time however, would it make sense that all other apps are working fine? I have no problem downloading anything, watching movies from my 5 movie apps, connecting to the internet and my wife has no problem using her Cricut online!
Just changed out my router and Roku channel started working! Like you I doubted it was the router as everything else worked fine. Changing the router worked for me and solved the problem.
BTW I was using a mikrotik router RB750Gr3 using the current router OS firmware. I must have lost the Roku channel after an upgrade.
