Using LWP Proxy and Client Certificate Connection timeout

[kabachaa]

I am new to perl, below is the code that I have compiled and run to connect using a proxy to get response from the server which requires a client certificate. I am trying to figure out if issue is with my script or on the other end at the host site. Can someone please look at it and give me some directions how i can debug and see the problem. I get error 500 connection timeout when I run this script. Thanks
