Hi @kb1,
If the page is blocked you should see this in the log of the firewall or in the log of Symantec (Bluecoat) SG.
It's the wrong forum, but I can help you on the Bluecoat.
Create a trace file on the Bluecoat with the following steps:
1) Creat a new "Web Access Layer"
2) Move the Web Access Layer to position 1.
3) Now creat a rule with the destination www.trello.com and an action "trace file"
4) >>> Open the URL on the browser
5) Now check the trace file on the Bluecoat SG under https://<Bluecoat_IP>:8082/policy/ -> trace files
At the same time check the following on the Check Point gateway:
1) Resolve the IP via DNS name www.trello.com
2) Start "fw ctl zdebug drop | grep <www.trello.com_IP>
3) >>> Open the URL on the browser
This should let you see who is generating the issue.
Regards
Heiko
