Issue With mqtt_simple connecting to AWS on one of my nRF9160 DK boards

[JLCIOT]

I have two nRF9160 DK boards that are programmed with modem firmware version 1.1.1 and are using V1.2.0 sdk software.  They also are both programmed with the same mqtt_simple code.

One of the boards is able to connect to AWS and one of the boards is not able to connect.  It does not make sense to me how this can happen.

Provided below is the error code that I receive in the UART window on the board that is not able to connect.

Any suggestions on what my issue is and how to correct this error would be greatly appreciated.

Can you check if the SIM card you're using is out of data/nearly out of data? I assume that is what's causing this. Either that or the SIM you have is damaged/broken. I suggest contacting the SIM providers if you have questions about this.

Please note that we're entering the summer vacation period here in Norway, so delays must be expected as we are low on staff for the month of July. Sorry about the inconvenience!

Best regards,

Simon
