Problem solved.
If anyone finds same issue, I had erased the "Baltimore CyberTrust Root certificate".
This certificate can be easily downloaded from the web and must be updated to the CA certificate field.

Thanks for the fast answer.
For creating the certs I've been using the next guideline:

https://docs.microsoft.com/en-us/azure/iot-hub/tutorial-x509-scripts

Then, with the Certificate Manager of the LTE Link Monitor, I've added the client certificate and the private key to the nrf9160dk.
Doing this, I could connect to the hub but since I've deleted all the certificates I cannot reconnect again.

Could I be missing something?

Hello Angel,

you can use the Credential storage management %CMNG command to delete all the certificates stored in the modem.

Afterwards, you can create a new nRF Connect for Cloud certificate. This should restore your modem certificate settings.

I’m not quite sure if deleting other certificates is related to your connection problem with the Azure Hub, though. Each modem socket uses his own security tag that is allocated by the application.

I hope this will help you!

Regards,

Markus
