EndOfStreamException : Failed to read past end of stream

So... finally decided to give up struggling and post a question :) I've been looking for some answers online but couldn't find anything related to this specific issue.

I've written a client-server application in unity 5.0.2 and when receiving a response for a message i'm sending (btw the message arrives fine to the server) i get an exception. The weird thing is that when i execute the same code in visual studio or the compiled executable i don't get this exception
