Hello, so if you have not seen my snippet post it is located here so that you are able to understand the circumstance of this error.
[508] RSPS C# Rework

The current problem with the media on that page is that the chatbox interface is not being display this is down to either a disconnect from the server or bytes not being sent properly.
On another note it appears that the packets are not being handled properly, although it does not output successful packets it should atleast output unhandled packets at this point.
If you need any segments of code just ask below.

The main error is that the client loses connection with the message "No connection recieved" and then disconnects.
