Re: How to debug this?

My client and listener can connect fine on 127.0.0.1 port 9005. However,
once I upload the listener to my webserver and change to the web server IP,
I get the error below:

An unhandled exception of type 'System.Net.Sockets.SocketException' occurred
in system.dll

Additional information: No connection could be made because the target
machine actively refused it


I tried the IP address TcpListener() (on the server) as the remote server
and also as my local computer public IP. No luck. What could be causing
the above and how can I correct it?

Thanks,
Brett
