Socket error on client ***, disconnecting while trying to subscribe through robot framework

[aswathykrishnan92]

So. I have brought up a mosquitto broker using mosquitto -v. I have subscribed to topic MQTTTest2 and published for which I am getting the publish message correctly.

I try to replicate this via robot framework. I am able to publish a message just fine. But when I try to subscribe to the topic, I am getting a socket exception

Below is the code I used:

Publish
    Connect     127.0.0.1
    Publish     topic=MQTTTest2   message=test message
    [Teardown]  Disconnect`
Subsribe and Validate
    Connect                 127.0.0.1  client_id=1589-BLRKEC3344
    Subscribe and Validate  topic=MQTTTest2    qos=1   payload=test
    [Teardown]              Disconnect`

The publish part is working fine and I am able to see the message in cmd window. But the subscribe part gives socket exception. Please not that I have given the clientID randomly with refererance to the Ping request from the other subscribers already started. I tried with and without client id. I am having the same issue. Please help me out?

From what I can tell, you're saying that mosquitto_sub and mosquitto_pub work ok, but the robot framework has problems, is that correct? If so, you might be better off asking for support there instead.
