    Hi!

    From the log file, I can see that you don't have coverage where you are. So you aren't connecting to a network which is why you can't open a socket and are getting an error from the modem. 

    Are you sure your SIM card supports for LTE-M or NB-IoT, and that there is coverage where you are located?

    Best regards,

    Heidi

    Hi,

    I am quite sure about the network and the Sim Card as the other MQTT application which I downloaded was working and had no issues as far as network coverage.
