Thanks that helped a bit. And i found a solution after me and my bro took a closer look in that thing. After we could't play some more downloaded games, we found out that some security tools which scan downloaded files were diving into the IL/bytecode to scan that. If there are c or c++ .h bindings and is has something to do with network connection they put the whole DLL on the blacklist. So there was no need to be a network expert to get this LOL. Whiped it from the blacklist and it wasn't shut down when internet is connected. This was  very helpful for me because i also want to provide clean software. Maybe this link can help you: stackoverflow.com/questions/47247888/how-can-i-exclude-unnecessary-dlls-from-my-build
So my fault, delete the whole thread if you want, because its developer stuff.
