HTML5 Project Not Compiling when externally hosted

I have compiled my project into HTML5 files, it works fine locally. But when I host the files externally (via S3), it doesn’t compile, it downloads the files and does load the progress bar fully, but crashes before launching. I am running this on OSX 10.9.5 64-bit machine.

I get the following console error when running Chrome (V47.0 64-bit), the screen output is null:

Uncaught abort(143) at Error

If this abort() is unexpected, build with -s ASSERTIONS=1 which can give more information.

I am not sure what is causing this error.

When using Firefox (V43.0.1 64-bit) I get the following error output on screen:

b143
FMemory::Malloc(unsigned long, unsigned int)
operator new()
undefined TBaseDelegate?9()
undefined?C? FStaticallyLinkedModuleRegistrant?2()
__GLOBAL__sub_I_Module_Launch_cpp

And the following console output:
