As I said, it looks like the server is closing the connection, which leads to POLLNVAL and "not connected" errors (-57) on your end.

Are you trying to connect to nRF Cloud or your own AWS instance?

Have you verified that you are using the correct client ID, and connect to the correct endpoint?

Do you get another error earlier in the log?

POLLNVAL is usually because the socket has been closed from somewhere else.

Have you also checked that the client ID and endpoint that you try to connect to is correct?

Hi.

This is the intended behavior.

You are only allowed to read back CA certificates.

Merry Christmas!
