Zero Touch Onboarding Connection Fails During Initial Setup or After Reset

Symptom:

The system fails to connect to the Zero Touch Onboarding (ZTO) service during initial setup or after a system reset.

Problem:

The system can’t communicate with the ZTO service because of a firewall and/or web proxy setting.

Workaround:

Configure your firewall and/or web proxy so that the system can communicate with the ZTO service (zto.poly.com) on port 443.
