Ticket authorization failed. Reused Ticket [STEAM API]

Im getting this error while handshaking with the server, I am the server owner and I would like to know what can I do:

I have tried to know if my API Key works and it does work, I used this command to test: curl --http1.1 -X GET “https://api.steampowered.com/IPlayerService/GetOwnedGames/v1/?key=MY KEY&steamid=RANDOM STEAM ID” when the key its not working it returns {}, if it is working it will return the correct data. So I tried to change the key after getting this error for the first time and it worked for a while, but now its happening again. Maybe is steam limiting the api calls? I don’t think so, the limit is 100.000 per day and I only have 100-110 players.

The new key I added that is passing this “test” I made, so I really dont know what is happening.

The error also goes by: HTTP/2 stream 3 was not closed cleanly before end of the underlying stream - CURL error code 92 (Stream error in the HTTP/2 framing layer)
