you need to affect the network interface to the firewalld zone:

public (default)
interfaces: 
sources: 
services: dhcpv6-client dns http ssh
ports: 443/tcp 80/tcp
masquerade: no
forward-ports: 
icmp-blocks: 
rich rules: 

With
firewall-cmd --permanent --zone=public --change-interface=NAMEOFINTERFACEand reload

Do you actually have something running and listening on port 443?

ss -antup | grep LISTEN.*443
