Yes i tried the MQTT connection on my computer :

No I didn't configure the TLS function, should we just modify the concerned line in the <prj.conf> file :

To save the changes made in the prj.conf file, should we just rebuild and run the solution?

Please provide full LTE Link Monitor output to verify the connection.

Have you verified the MQTT connection on your computer? As there is no errors, I can't see that there is an issue. Try adding CONFIG_MQTT_LOG_LEVEL_DBG=y to our project as well. This should give more information on regarding.

Have you verified that your setup is configured for TSL? From MQTT.org: TCP/IP port 8883 is also registered, for using MQTT over SSL. Have you tried with port 1883?

Hello,

Have you verified that your device is connecting to the network? CSCON: 0 indicates that it is not connected. Can you please try with another sample. e.g. AT Client to verify the connection?

Kind regards,
Øyvind
