LWM2M Client in nrf9160 Feather Failed to connect with Leshan server

I uploaded nrf9160dk working code in nrf9160 feather board file. before upload the the code i added the new board circuitdojo_feather_nrf9160_ns in application section. Build was completed successfully. UART logs mentioned below:

—————————SIM Details———————
First time i use Hologram sim which comes with nrf9160 feather . Same error as above
Second time i use working i-Basis sim which comes with nrf9160-DK board and successfully tested with Leshan server but with nrf9160 Feather i am getting same error.

Could you please help me to resolve this issue.

Hi Deepak,

Unfortunately, I haven’t use the LWM2M client on Zephyr that much. But if it’s working on the nRF9160DK it should work on the nRF9160 Feather. One thing I’m not seeing from your log is any connection information. You should add some debug messages to your connection dialogues to make sure you’re connected to NB/LTE before establishing your LWM2M connection.
