We just migrated to MWG 18.104.22.168. I have been facing two issues.
1) In IE, the users occassionally get the authentication pop up. They can continue to access the site after entering the prompt.
2) I have noticed in some cases, eg nessus registration, the registration fails giving a CONNECT error., rule tracing shows that it stops at AD authentication. Upon skipping the AD authentication the registration becomes successful.
The same issue used to occur when I access a proofpoint link (https://urldefense.proofpoint.com/v1/url?u= "some site") which is opened in a IE from outlook, its takes a long time to load. If I click enter on the link in the browser is loads immediately. After bypassing AD authentication for the link, the site now opens without any problems.
I am using the below guide for the Proxy HA.
Thanks in advance.

Issue has been solved. The IPS was blocking the 407s. After whitelisting the same, the popups dont appear anymore neither do the websites slow down.
