A Connection to the MDM server could not be established

Problem

You have scanned the QR Code and downloaded the MDM Profile. However, while installing the MDM Profile, you encounter the error: "Profile Installation Failed. A Connection to the MDM server could not be established."

Cause

• Device Connection to the Server
• Blocked URLs from firewalls

Resolution

1. Device Connection to the Server: The device might be unable to establish a connection to the MDM server. Ensure that the proxy or firewall is not blocking the device's connection to the server.
2. Blocked URLs from firewalls: The necessary check-in URLs for iOS and Mac devices might be blocked by the firewall. Verify that the iOS check-in URLs (NAT Address/mdm/client/v1/ioscheckin) used by the device for enrollment are allowed through the firewall. Additionally, confirm that the Mac check-in URLs (NAT Address/mdm/client/v1/maccheckin) used by the device for enrollment are permitted through the firewall.
