Mosquitto TLS connection

Configuration
1

Hi,

I am running Mosquitto Broker within HA and noticed that it using port 1883 which documentation says is insecure and can be disabled. So I made following changes:

  1. Disabled port 1883
  2. changed the configuration setting “require certificate to true”
  3. In the ssl folders there are two files namely “fullchain.pem” and privkey.pem"
  4. Restart Mosquitto

Now when I try to connect to MQTT broker on port 1884, 8883 or 8884 - I am not able to connect.
Did I miss something from above steps or did not follow the documentation properly?

Thanks.
