I am using self-signed certificates and have already verified that valid communication using a node js server and client using the same certificates and keys.  However, I cannot connect to the emqttd broker via TLS.  I don't receive an error message in my node app or see any errors in the emqttd logs.  Does anyone have any experience with Node JS and emqttd using TLS?  I have no trouble using TCP.

It might help if you take a look at the page: https://www.digitalocean.com/community/tutorials/how-to-install-and-secure-the-mosquitto-mqtt-messaging-broker-on-ubuntu-16-04

There he clearly specifies how he connects using:

mosquitto_pub -h mqtt.example.com -t test -m "hello again" -p 8883 --capath /etc/ssl/certs/ -u "sammy" -P "password"

And this works from a remote server as well. It means even for cert based authentication the username/password needs to be provided for mqtt.

Now please try to follow this pointer. Incase if you have already solved the problem would like to know how. 

regards.
