Hi Jorghy
I have not seen it, but it may simply be that the MacAffee product tries first of all to connect to that site for whatever reason and PAM is just preventing the connection. I would suggest 2 things
1. To see if this is something which the MacAffee product does on its own, install fiddler on your machine (you can retrieve it from www.telerik.com) and see if the connection to the MacAffee portal outside of CA PAM invokes any type of traffic going to client1.google.com. Fiddler is, as you know, a utility to track http traffic. You may as well use F12 de tools from Chrome or any tool of your choice
2. To see if this is related to PAM itself, try with the native browsers. Same problem ? Also, if you connect to any other portal using the native browser, do you experience the same ?
I would strongly advise you to open a case for this, nevertheless as troubleshooting may not be easy here.
