Today I was met with error code 73 when trying to login to Disney Plus on my Apple TV. Their help article says you're either on a VPN or "Attempting to access Disney+ from a country/region where service is currently unavailable" which I obviously was not.
Despite lots of articles on the web saying to trying rebooting, reinstalling, and the like, none of that worked (although I did try it anyway) because what had actually happened was Disney had blocked my IP address. I know this because when I got on live chat, explained the situation, they asked for my IP (by sending me to this ad-riddled website) then they "refreshed my IP" for me which magically fixed it. Yep, refresh the IP address, thats a thing.
No amount of rebooting was going to fix that. Next time, I'll just go straight to the live chat.
