Accepted Answer

At high level it seems connection issue - 3 things can hint based on analysis of your logs-

1)
uart:~$ [00:00:00.599,243] net_sock_tls: No entropy device on the system, TLS communication may be insecure!

But I see some certificate too being used at end of logs

2)
uart:~$ [00:00:00.642,364] SEC_INTERNAL: sec_int_start: start
Here the discovery is started but messages are getting dropped.
uart:~$ uart:~$ uart:~$ mctp discovery completed. service initialized.
--- 5 messages dropped ---
[00:00:01.159,606] SEC_INTERNAL:

3) Waiting for DHCP to assign address

May be this would help :https://learn.microsoft.com/en-us/azure/iot-central/core/troubleshoot-connection
