Looks like the website url to get to the live feed changed.
It's now at https://www.nfl.com/network/watch/nfl-network-live
And after I link my Provider, the video doesn't load. Just a spinning circle. Even after refreshing the web page. Using Firefox.
Just tried using MS EDGE and it works at their website.
Now working with Firefox too.
Channels DVR still doesn't work.
