That means it's open from the firewall side, but nothing is listening on the port.
Which is interesting because `ss -tapn` shows otherwise and the log for mosquitto agrees:
1723324003: Config loaded from /mosquitto/config/mosquitto.conf. 1723324003: Opening ipv4 listen socket on port 1883. 1723324003: Opening ipv6 listen socket on port 1883. 1723324003: Opening ipv4 listen socket on port 8883. 1723324003: Opening websockets listen socket on port 443. 1723324003: mosquitto version 2.0.18 running
