Google updated Chrome’s handling of local device and local network access, so this setting must now be explicitly managed through Group Policy. This should be deployed as a mandatory machine-level browser policy using the latest Chrome ADMX/ADML templates, following the same centralized administrative template model Microsoft documents for Edge.

​
Required Configuration

Allow TruU domains to access other apps and services on the device using this value: [*.]truu.ai

​
1. Download the latest Chrome policy templates

Go to the Chrome Enterprise download page, select Management, choose Chrome ADM/ADMX templates, and download the package.

2. Import the Chrome ADMX/ADML templates

​
3. Open the Target GPO

In Group Policy Management Editor, edit the GPO that applies to the target Windows devices.

​
4. Browse to the Chrome policy

Navigate to the Computer Configuration → Policies → Administrative Templates → Google → Google Chrome → Local Network Access settings. Then, open Allow sites to make network requests to the local device.

Once applied, TruU browser flows that access local device services should now be properly allowlisted.
