1. if you cant open ports u wont make it work
so open ports 44405,55901,55919 and run server.. then go to
www.portchecker.co and check ports 44405 if running or 55901 too, if sucess then its not port issue its bad config in client issue or server files ip wrong configuring, simple as that, my tutorials are not 'mismatching' it should be all easy and clear of what to do, those files are old anyways thats why u get confused easily.. so figure out about ports or else if port shows failed on the porchecker website use your IpV4 ip in files and client in order to be able to connect just your self u can find ur ipv4 if u go on pc> start> command prompt type ipconfig and use the IpV4 instead then u dont need open ports, if still issues then still u didnt edit files,client correctly with hex editor and all that, and we cant help u if we dont see exactly images of how u edited things at all.
ps the client and the files are downgrade of s4 to season 2, thats why u think its s4... if u want a classic s2 check my older videos, but those files arent stable in the long run.
