Unable to fetch Rapid Games

I am trying to fetch games of 10+0 time control using below links and it errors out, but this url is working for other users.

https://api.chess.com/pub/player/muzzleplayer/games/live/600/0

Any idea what is wrong here?

That URL works for me. I did not know you could search for time controls like this!

That's been around for a while but I think could fail on members with a lot of games.

Wow, that returns the full PGN for all games in those time controls? that seems like it would be a lot of work to generate
