FQDN Very Slow USG Flex 700h V1.40(ABZI.0)

What I might suggest is if the IP is static for drive.google.com where you are maybe just allow by IP and if you still have issues then you know it not that.

Hi, I didn't include some pages because I already have them enabled in other policies, since they depend on other services, like gstatic, which isn't only used by Google. The problem is indeed the FQDN, because if I fix the IP address as you suggested, it works perfectly, but it loses its appeal because those pages change their IP addresses from time to time. Hopefully, Zyxel will improve the FQDN system or add a button to force IP address population, so it doesn't automatically populate the IP address the first time and avoids the long wait for it to obtain it automatically. Thanks!

As I said the FQDN works find its just the UI thats slow I have over 600 FQDN I have a FQDN that is vpn.bridgemode.network where by on my phone by cellular if the IP does not match it is blocked I then do DDNS which updates vpn.bridgemode.network IP and within 2 minutes I can connect.

The Expire cache by TTL should by on for like vpn.bridgemode.network but wildcard FQDN can work better with that option off.

I suggest you try *.google.com for some days to see if thats stable
