On CentOS7 I have following firewalld setting.

external (active)
  target: default
  icmp-block-inversion: no
  interfaces: eth0
  sources:
  services: dns ftp http https imaps pop3s smtp ssh
  ports: 110/tcp 21/tcp 20000/tcp 106/tcp 53/tcp 990/tcp 5432/tcp 8447/tcp
113/tcp 143/tcp 3306/tcp 5224/tcp 22/tcp 465/tcp 995/tcp 25/tcp 10000/tcp
8443/tcp 993/tcp 443/tcp 8880/tcp 587/tcp 20/tcp 53/udp 12768/tcp
  protocols:
  masquerade: yes
  forward-ports:
  sourceports:
  icmp-blocks:
  rich rules:

But by ss -nat, IPV4 443 is not listend. How can I fix?

# ss -nat | grep LISTEN | grep 443
LISTEN     0      128         :::443                     :::*
