Question : ssl no longer working, "Data Transfer Interrupted"

I'm developing a web application using JDeveloper 11, Weblogic 10.3, CAC/DoD certificate authentication, JKS keystore. When running my application, I can connect fine over HTTP, but when connected over HTTPs, in firefox I see "data transfer interrupted". There is no traffic showing in firebug (no requests/responses). I am able to connect to other HTTPS sites ok and using my CAC.  I have triple checked my keystore settings and restored it using a working copy incase it got corrupted.

I have read online that virus protection may interfere, but I tried disabling my symantic end point protection. Also the windows XP firewall is disabled.

The hosts file looks like:
127.0.0.1 localhost

Any tips or suggestions appreciated. Not sure where to look from here.

Answer : ssl no longer working, "Data Transfer Interrupted"

Ran netstat -ao and found a process binding to port 443

After running taskkill /PID on that process I noticed Skype closed. Apparently skype runs a P2P client in the background, which opptionally uses port 443/80. You can disable this in advanced options.
