Just migrated GC from 4.3.6 to 6.0.1. If I now test connectivity on the MARS IPS signatures dynamic updates page, I get internal error. I'm using Proxy as well. If I change URL https://www.cisco.com/cgi-bin/front.x/ida/locator/locator.pl to http not https, I can see MARS request hit proxy and proxy try to connect to http page. If I use the default https URL, MARS makes connection to proxy that appears to be rubbish, so proxy doesn't send out https request. In fact any https request doesn't work from GC anymore, only http. Any ideas??
