Well no that's not a correct send to server hook, the byte length is 7 not 5, you're hooking instantly, hook only ingame and hook outside of the match or else HShield will detect it and crash you. Basically remove the detour you have created once you're out of the match, also find another method to hook the s2s address, for example, hook it via CShell, find the address which calls back to the S2S address in Engine.exe and hook from there.
