We have configured Defender Application guard Enterprise mode in Intune for testing purpose but not working in corporate network. But when we connect public network like mobile hotspot it is working fine as expected,

Trusted cloud resource is added for testing purpose in Application guard configuration setting that's opening host Edge browser, but issue is when trying to access Untrusted URL or Cloud resource, Container browser is opening in Edge, but issue is getting error site can't reached and site is interrupted. So we have added Enterprise proxy IP address in setting with port number and without port number Example: x.x.x.x:8080 and x.x.x.x:80 and x.x.x.x but still we are facing same issue, please help us to resolve this issue and we tried everything as per Microsoft recommended.
