Using Apple TV, suddenly discovery + thinks I am in Canada. How can I fix?

My Apple TV and discovery plus service worked fine on 12/31/2023. On 1/2/2023 when I opened Discovery+ it asked me for my password, then told me I had Geoblock Error 401, different country from initial setup. Then gave me a link to Discovery plus support in Canada. This is obviously something that was triggered by an update over the new year. I have troubleshooted for hours with Apple TV and discovery plus but they have no idea except to clear my cache. I have done that in all the ways I can, unplugged and replugged everything but no change. Anyone else heard about this happening?
