United States TV 247 and United States TV Go are two well known and pretty reliable free IPTV sites but they haven’t worked for me using W10 FF75 browser for a week now. I connect through NordVPN and the video player returns a “problem playing protected content” error message no matter what channel I select. Tv Go works fine on my iPad using Nord, haven’t tried 247. What gives? Both sites would have sporadic issues from time to time but for them not to work for a week seems unusual.

Update - I was able to get video to play in Brave browser with the guards set to off. I am not entirely comfortable streaming from these sites in that way. My FF browser instance is pretty locked down with plugins and about:config settings. I did troubleshoot the plugins with no luck will do the same in the settings.
