Oh it fixed mine immediately. I even went back and tried nord which still gave the error message. Leads me to believe it’s the connection location so maybe go through all the USA cities in nord and Proton. I use ‘fastest US server’ on Proton btw.
That’s brilliant. After months of having the same problem I am glad I could share the fix.
You’re most welcome. I honestly feel your pain because I was going through the same thing. Hopefully this fix stays good so we can all enjoy what we are paying for! Have a wonderful day! 
Big ups all around, super appreciated
Thanks but just tried this and it doesn’t work for me. Wondering what else I could be missing. I even reset the fire-stick after. Do you use split tunneling to leave out prime video?
Yeah, I had it connect to same in Proton. I’m in the US, btw. Might choose around some other servers in Proton and see what happens. In the meantime, if that doesn’t make for a workaround, I’ll watch AP even less than I do now (since the Ads!) and use it as a list maker for things to watch someplace else. Am going to ONN sooner than I thought perhaps.
No, I didn’t change anything other than that, sorry.
