Hi friends, I am facing an issue when one of my developers is trying to access ebay api thorugh code on the dev server. He is not able to get it work, the connection doesn't go through. It works fine on another server which is not behind ISA. The issue is , I get failed connection attempt and closed connection. Also another thing I noticed was, when I connect to other SSL sites .. using https:, in the logs I see the protocol as ssl-tunnel. But when I try to open this ebay api link, https://api.sandbox.ebay.com <https://api.sandbox.ebay.com/> <https://api.sandbox.ebay.com/> I get the protocol as HTTPS. But both show the port as 443, then why different names.. can this be the issue. I am really confused and need some help to get it working. The server is configured to use proxy using automatic config script. And the firewall rules have http/https access to the site for all users. Any ideas.?
