Thank you so much for your help.
You can start with a PCAP as "ip host x.x.x.x or host siamcement.csod.com or port 53" . Access the site when this is running and see whether the proxy is able to reach the server in time.
start PCAP in the ProxySG
start PCAP on the Firewall
Check the logs on your FW, IPS and other devices
in CLI run a test http get to siamcement.csod.com and check the log in the fw
I'm waiting information from customer.
if you run a policy trace, you should be able to easily see if it is the proxy causing the issue or not.
The following article explains the times seen in the policy trace:
