Fitbit pay error 500

[mkan0]

Had to remove my curve card to add the new one, but it fails when contacting the bank with error 500.

Have done this many times in the past, this time it doesn't work no matter what I try.

Reinstalled app, unpaired device, restarted device, cleared watch data (factory reset), still the same.

Is there any chance it's a problem with Curve website? Should I contact them?

Thanks in advance.

It's very important for me, I use it everywhere all the time

For anyone looking for answers to the same problem, tried next day with the exact address stored in my curve banks records (had a typo in the post code and a comma after the street number) and that must have been it, then it worked.

Still, 500 internal server error is not intuitive, it would be better described as "records do not match" or something
