Hi!
I’m developing a SW to connect with mosquitto broker. I started from the source code in apps/platformservices of Legato environment.
I can right build the project, create the session, but I have problem when I have to connect to the broker (both if i give mosquitto or AirVantage adress broker):

I’m trying to connect without user and password (I’m beginning!) and this is the result:

Obviously I connected my mangOH green to internet thought both WiFi and Sim and I can righly ping google, so it is not a connection trouble. Mosquitto is running on my VM:

Can someone help me to understand the cause of this problem? Here is the code I’m working on…maqqClientServicee.txt (36.7 KB)
Which could be the problem?
