Running Docuware Sample Node.JS Validation

So I am trying to run the sample node validation on my local server and have it accessed from Docuware Cloud system.
I followed instructions to download/install/configure and run the supplied sample. It is running, but I can't access it from my cloud system.
Are their any missing requirements for my local server, such as open ports, SSL certificate, IIS iconfiguration to make this to work (So far I opened port 4444 but that did not make a difference)
Has anyone got this to work and would share details?
Thanks in advance.
