I have a customer who can't reach a specific site. I know the IP of the site, and can see the Ironport make the Proxy connection on the ASA to that IP, but they are getting a spinning wheel and eventually page times out. If they connect to their guest network which bypasses the Ironport, they can get the page just fine. So only thing in the middle, the Ironport.
When I review the logs for the domain, they come up empty. What can I look at to see the connection details and find out if it is the Ironport?
