Comprehensive and Detailed Explanation From Exact Extract documents and Knowledge:

By default, FortiGate ' s security engines are configured to recognize specific protocols on their standard ports (e.g., HTTPS on 443). When traffic uses a non-standard port like 8443, the firewall may not automatically recognize it as HTTPS and thus will not apply the appropriate SSL inspection or category-based filtering. To resolve this, administrators must update the protocol port mapping within the SSL/SSH inspection profile. By adding port 8443 to the mapping for the HTTPS protocol, the FortiGate is instructed to treat traffic on that port as encrypted web traffic, allowing the full SSL inspection engine to decrypt it and enforce the FortiGuard category blocks as defined in the policy.
