packaged exe main script crashing without internet access

[JackGit3]

If I run it in the editor with or without internet everything still works just fine. However in the packaged version if I turn off my internet connection then the mainscript crashes every time. Where would be a good starting point for me to dig into this issue or would anyone perhaps know why this might be happening?

What does the log say? this is where the wrapper script starts, you may want to trace it from there to see where it could be crashing: https://github.com/getnamo/nodejs-ue4/blob/master/Content/Scripts/nodeWrapper.js#L101

I have exactly the same issue. If I shut down my network card the node process doesn't start.

I need a bit of a test and end up binding HTTP to 127.0.0.1 instead. of localhost.

Inside: Plugins/nodejs-ue4/Source/CommandLine/Private/NodeCmd.cpp

-   Socket->Connect(FString::Printf(TEXT("http://localhost:%d"), Port));
+   Socket->Connect(FString::Printf(TEXT("http://127.0.0.1:%d"), Port));

Inside: Plugins/nodejs-ue4/Content/Scripts/nodeWrapper.js

-http.listen(k.port, ()=>{
+http.listen({
+   host: '127.0.0.1',
+   port: k.port,
+   exclusive: false,
+   readableAll: true,
+   writableAll: true
+}, ()=>{

Exclusive is default to false, so should be useless, and believe the readable/writable should be too, but we launch our game as admin (Kiosked PC)
