When I go to the Netflix channel on my cable box, I get the spinning circle for a while, then the error message
Couldn't connect to Netflix. Please try again or restart your
home network and streaming device. For more information,
[Try Again] [More Details] [Exit]
Try Again just gives the same error again. This had been happening on and off, but now it's every time. I can get to Netflix just fine from my computer, phone, and Amazon Fire device.
Try: Main Menu > Settings > System Information, scroll to page 2, hit OK to reset the Netflix app. Power cycle the box, you should be OK.
