Is it on all API endpoints or a specific one?
Also, is your user-agent configured correctly?

The Public API doesn't use credentials, so the account doesn't matter.
So I have a python program that's querying the API and it's been working fine. A week ago or so I told support I had two accounts and it was approved. Well, now my program has been fine making calls to get PGN data from my newer account, but today I went to pull PGN data from the other account (SimpleChessBrah), and the JSON returned is an error message with error 503, with the message:
An internal error has occurred. Please contact Chess.com Developer's Forum for further help https://www.chess.com/club/chess-com-developer-community
Help would be appreciated.
