GP connected by not able to access resources Internal and Internet

[Khairul.Nizam]

I have 2 firewalls deployed Active-Passive in cloud. (AZ1 & AZ2)
Both configured with GP Portal and gateway.
When users connected to AZ1 using GP. No issues & normal. 
But for AZ2, able to connect to GP, but when connect, not able to access and browse to the Internet and Internal resources. 
I try to follow what ever config done in AZ1, but still not find any discrepancy. 
How can I check what is missing? any area that I need to check ? or which log can be checked ?
