Hi Andreas,

Basically, this is not a bug but rather a limitation of the Modem. nRF9160 modem firmware does not support sendto operation for TLS/DTLS sockets at the bottom level, while this step is conducted by the net_lwm2m_engine maintained by the Zephyr project from the application side, so you get this error to repot from debugging information.There should be no influence on the MQTT transmission between your client and server.

Currently, we are working on some other higher priority tasks but we do have a plan to investigate this limitation further. Thanks for reporting this to us!

Best regards,

Charlie
