I am using paho mqtt for one of my deepstream projects.
It was fine to use in local deepstream installation.
But in docker, I can install but when run to test the following command

paho_c_sub -t my_topic --connection tcp://localhost:1883
I have Connect failed, rc Failure

Tried a few options like, but all failed. What did I do wrong?

I have Connect failed, rc Failure

seems it is the network issue. please refer to the doc to start docker.
