Issue Description
When setting up Cisco Security Connector with Jamf School, the DNSProxy Profile may fail with the error: "Error loading umbrella configuration."
The issue arises from using the $SERIALNUMBER variable instead of the %SerialNumber% variable when configuring the DNSProxy Profile.
$SERIALNUMBER is used by Jamf Pro.
%SerialNumber% is used by Jamf School.
Troubleshooting Steps
Update the Variable Format.
Replace all instances of $SERIALNUMBER with %SerialNumber% in your DNSProxy Profile configuration.
Apply the Updated Profile.
Save and reapply the profile to affected devices.
Verify Configuration.
Check if the DNSProxy Profile is functioning correctly without error messages.
