WSo2 EI Error: Port Number missing from URI - wso2

Question

I have created a file transfer application using Integration Studio for WSo2 EI, it is a bi-directional flow so I am sending and fetching to/from a server. I have done many of these in the past and they are quite simple however I stumbled upon the error below today when deplyoing the application. I dont undersand why I am getting this as the port number is clearly specified and as I mentioned I have done these in the past before and applications with exactly the same URL layout are working so I dont know what could be wrong. Does anyone have an idea of what might be happening?
