I figured it out.
There are no more multipacket answers from the CS2 server. Only NodJS was the limit with 64K/packet, so I had to reassemble them.
Also the CS2 server does not seem to send two packets on authentication, but only the real authentication-response.

So I could update my Server API to run with Linux CS2 dedicated.
