The fact that you're seeing this when running them both on the same system is very odd. Among the things that I'd look at are any security software that might be mangling the communication - either A/V software on the Linux system, or a Web Application Firewall or Deep Packet Inspection firewall that could be blocking something. Have you modified the code at all - any changes to the server or client? Or are you just deploying what you've downloaded from the web site? -NIck
