Hi @CyberEye ,

Do you have an IoT license? The grpc is used to interface with an IoT cloud tenant.

No IOT is not configured

Take a look at the command 'show ctd-agent status security-client'. This should give some details of why it is failing along with the current connection status along with the server that it is trying to connect to.

Make sure you have a valid Device Certificate and the Management Interface/service route (Palo Alto Network Services) is able to reach the the URL(s) being called.

Also ensure that the OCSP urls that Palo Alto uses are also accessible over port 80:

• http://ocsp.paloaltonetworks.com
• http://crl.paloaltonetworks.com
• http://ocsp.godaddy.com
