better allow concurrent API streams

User feedback:

I wanted to use 2 streams
/api/stream/games-by-users to monitor all the games between our club members
/api/stream/games/{streamId} to monitor additional games our members are playing with other people so we can show whether they are available or not

The trouble is that having the 2 streams open, blocks me from making API calls that are needed in parallel. I get the error that I should not be making more than 2 request at the same time.

When I am connected to the 2 streams, any API calls I make (even single ones) return a 429 error. The ones we mainly use are these:
/api/users/status
/api/user/{username}/current-game
/game/export/{game}
/api/games/user/{username}
/api/challenge

I can't reproduce it with the first endpoint mentioned, /api/users/status:

Here I'm streaming /api/stream/games-by-users and /api/stream/games/ simultaneously, yet I can still use /api/users/status without being limited.

You are right, not all API calls fail (at least not consistently)
I will try more. So far:

• /api/users/status WORKS
• /api/games/user/{username} FAILS
• /api/user/{username}/current-game WORKS
• /game/export/{game} WORKS

[andreasantoniades]

So it seems to only be /api/games/user/{username} from the ones I checked. Apologies for the confusion, I listed the APIs we are using, not the ones that are actually failing.
