Create a new access control policy rule to allow ports 80 and 443 to the FQDN of the web server.

Identify the blocked traffic in the Cisco FMC connection events to validate the block, and modify the policy to allow the traffic to the web server.

Verify the blocks using the packet capture tool and create a rule with the action monitor for the traffic.

Download a PCAP of the traffic attempts to verify the blocks and use the flexconfig objects to create a rule that allows only the required traffic to the destination server.
