GSuite apps not decrypted when using Chrome

L0 Member

I have seen some older posts with no updates on this very subject so I thought I would start a new thread.  I am testing SSL decryption from a couple of workstations and have almost all of the traffic being successfully decrypted.  We are a Google suite user with it being our email provider with our own domain.  I am on a mac and when using Chrome to access any of the GSuite apps, it is not being decrypted.  The cert is showing up as a standard Google Trust Services issued cert instead of my Palo Alto issued cert.  

I have blocked all QUIC traffic at the firewall per the Palo Alto published best practices.  I have a security rule with any as the source, QUIC as the application and services as Application Default.  Just to make sure something wasn't slipping past that rule I added another this morning blocking all udp traffic over 80 & 443 to no avail.  The logs show tons of blocked QUIC traffic from my workstation.  When I log into any of the GSuite apps from Safari, it is decrypted as expected.

Any suggestions?

Have you checked the Decryption log (monitor > Logs > Decryption) to see if it's being bypassed or failing?
