Hi Per,

You should increase CONFIG_MAIN_STACK_SIZE as you need more space for TLS certificates. The link I was referring to was just to point you to which define you should increase, not which value. Try increasing for 1024 at a time.

The old version of ncs used less of the stack so this is the only thing I can think of can be different when changing ncs version.

Best regards,

Marjeris

Hi Marjeris,

Unfortunatel, it must be something else as I already use these settings:

# Main thread
CONFIG_MAIN_THREAD_PRIORITY=7
CONFIG_MAIN_STACK_SIZE=4096
CONFIG_HEAP_MEM_POOL_SIZE=1024

Any other idea?

Hi Per,

It could be that certificates are not uploaded correctly because of the stack size being too small. Can you try increasing the stack size? https://github.com/NordicPlayground/fw-nrfconnect-nrf/blob/master/samples/nrf9160/mqtt_simple/prj.conf#L39
