Cisco is releasing an update to our Chromebook app. This release contains a change to the default DNS encryption port from UDP 53 to UDP 443 due to an observed issue in ChromeOS 99 and 100 (and above) that prevents blocks from successfully applying with DNS over UDP 53.
To restore DNS encryption on UDP 53, add the following to your Chromebook Umbrella configuration:
"resolverPortNumber": {
"Value": 53
}
Cisco Umbrella Chromebook client (Ext) - v1.3.4
Cisco Umbrella Chromebook client (App) - v1.3.15
