Hi , I haven’t been able to reproduce a crash in 4.7.3 when using 2 players. Does editor crash, or are you packaging game and game crashes? Are you using PIE or Launch? Can you walk me through exact steps you took to get this crash? Thanks! ---

Editor and game crash,no matter do I use pie or launch editor always crash. ---

So just to confirm: using PIE with Clients set to 2 in a new Blank Blueprint project will crash editor for you? ---

Yes that is correct. [Imgur: The magic of the Internet](http://imgur.com/y0CQWU2&sexgAHg#1) ---

Hey , It looks like you’re getting an error when calling GetHostByName that TranslateGAIErrorCode isn’t handling and check is failing because of that. We have a bug report for that in our system already (UE-9103), and we’re working on a fix that we hope will be in 4.8. For now, you can try adding " multihome=127.0.0.1" to your commandline (create a shortcut to Editor and add that to its Target). Otherwise, multihome needs to be IP address of server you’re connecting to. You might still have networking issues, but at least that should stop crash. ---
