Problem : I am attempting a TURNSocket (XEP-0065 – SOCKS5) using the iOS XMPPFramework and an OpenFire Server. I want to be able to send and receive files. However, in most scenarios, the receiver returns no response. I currently suspect the problem is to do with the OpenFire proxy server, which times out! This is set up on the local network, and I have edited the hosts file to point to it.
Note : The base of my code is from the following tutorial : http://mobile.tutsplus.com/tutorials/iphone/building-a-jabber-client-for-ios-server-setup/
XML and Error : The sender sends the following XML (after a few other XEP-0065 XML posts back and forth)…

If I chat to another instance of my app, I get the following error in the recipient when trying to use proxy.beta.myCompany.co.uk
Error Domain=GCDAsyncSocketErrorDomain Code=3 “Attempt to connect to
host timed out”
So my main question is, why did it timeout?
Extra Info : If I have a chat between one instance of my app and an Adium IM Chat client, I get no response. However, if I chat to a Spark IM Chat Client, I get the following response …

On OpenFire, I needed to set the ip of the proxy using a system property of ‘xmpp.proxy.externalip’.
