When I do:

`curl -s https://api.chess.com/pub/player/cheemsburger9000/games/2024/07/pgn -v > /dev/null`

We get this output:

This is reproducible on both my machine and my VPS which is in another country, through another network.

I can get, for example, 2025-06 games with curl -s https://api.chess.com/pub/player/cheemsburger9000/games/2025/06/pgn

But I've been retrying the other one nonstop with two-minute intervals between requests for the last day and I cannot get the request to complete successfully. It always sends the response up to some character, then it gets cut off.

Is this a bug? Am I supposed to stop retrying? I'm pretty sure this is not intended on your part, as I'd probably get a 429 error or something instead, if it was related to rate limiting or something like that.

Thanks
