Cable Provider Authenication Failed (Youtube TV)

Hey all, I need some assistance to figure out how to fix this. I was trying to record something tonight and all of the sudden, there was an error saying on the Schedule part that the Cable Authentication Failed.
So I tried removing the Source of Youtube TV and readding it, but during the Verifying part of my correct email and password that is associated with my Youtube TV account, it said Cable Provider Authentication Failed
Here's a picture from it. Can someone help me out here to figure this out? Obviously, it won't let me click anything on that Sign In picture you all see here.

I too see the same message when I try to set up my YTTV subscription credential for TVE. Wish it was as easy as adding Direct TV. But I can't get it to work either.

Same error for me

Seeing the same, tried on a two different Google accounts without 2FA or passkeys (one account just created) both can sign in to nbc.com, but can't be added as a source.
