Hi!  
I am using mangOH green with a wp7607 module. I want to enstabilish a mqtt connection using a Mosquitto broker. I want to use a Client based on paho on the mangOH.  
I downloaded this project from github:

> **[mangOH/MqttClient](https://github.com/mangOH/MqttClient/tree/use_paho_linux_version)**
>
> use\_paho\_linux\_version

I built it, changing in the file .c the port to mosquitto ( I don’t want to use AirVantage yet). I updated it on 192.168.2.2, but I see this error:

Which coulb be the cause?

Could be It a library problem only?
