C# tcp client dont work with GF login packet

DonkeyKong69XD · 2020-03-13T15:14:21+01:00

Hello, I want make login script with C#, but when I send login packet with tcp client i get "failc 1". probably there is something wrong with my login packet, but it is fine because I generated new login packet in C# and it works perfectly fine with QtTcpSocket. I dont know what to do, i tried few different tcp clients library and always i get failc 1. I don't know maybe it's this char between random hex number and nostale version, but i tried everything(\v; (char)0xB; tab; space) and nothing worked. Is there anyone here who wrote a working C# login to GF nostale and want to share knowledge?

Here is the code i'm using for a personal project and it work just fine.
Ofc you will need to modify it to make it work for you

Btw you're receiving failc1 if your client is outdated so it's probably coming from your hashes
