Traffic getting blocked due to missing security policy. Using an inband interface to obtain the device certificate from the CSP (Customer Support Portal ) requires a security policy to allow the traffic.

When using an inband interface (instead of the Management port) to connect to the Customer Support Portal to obtain the device certificate. Ensure the "Security Policy" is set to allow the traffic.
  1. Select GUI: Policies > Security and "Add"  a new rule.
