Unable to sign you into TurboTax Cloud. Please check your sign-in info and try again. error resolution

So I went to file today and was receiving this error when I tried to use my credit card to pay for state filing  "Unable to sign you into TurboTax Cloud. Please check your sign-in info and try again."

The kicker is that it has to be security related because I changed my PC's DNS addresses to 1.1.1.1 and 8.8.8.8 and everything worked fine.  Submitted perfectly, both Federal and State.  Only after getting super frustrated did I find a support thread mentioning something similar.

I've the same issue since last Saturday and have spent 5 hours on the phone with three agents with no resolutions.

I tried modified my IPv4 DNS to the settings you mentioned, 1.1.1.1 and 8.8.8.8 but I still failed to file both my federal and state (NJ) returns.

Help!
