Fantom VPM?

I have Paramount+ installed on ROKU connected to TMOBILE internet.

All in a sudden I was not able to see any content as it appears that Paramount + has found a VPN.

I did not install any VPN and on all ROKU receivers, iPhones and iPad I am not able to see Parampount + content. I can see only the ads during the interruption of sporting events.

Any clue on how I can proceed?
