Dell Online Support Experience Impacted Due to Local Network Access Restrictions

Impacts to the Dell online support experience with updated Chromium browsers

Customers visiting https://www.dell.com/support using newer versions of Google Chrome may encounter a browser prompt stating:

"Access other apps and services on this device"

Customers who choose Block may be prompted to install SupportAssist, even if the application is already installed.

Additionally, if the user selects Block, SupportAssist-related experiences such as:

• Driver Updates
• Hardware Scans
• System Configuration

will fail to function, even if SupportAssist is already installed.

More information on changes to Chromium browsers

Google Chrome version 141 introduced a Local Network Access permission model (now known as Apps on Device in Chrome) to enhance user privacy and security. This change restricts websites from sending requests to devices on the user's local network or localhost unless the user explicitly grants permission. This model has now also been implemented in Micrsosoft Edge.

These changes are part of broader efforts to prevent cross-site request forgery (CSRF) and fingerprinting attacks targeting private networks.

To determine your browser version, click the Menu (three vertical dots) button in the top-right corner of the window, then select Settings > About Chrome.

How to restore access to Dell.com support experiences

To maintain full SupportAssist functionality with Google Chrome, select Allow when you see the permission prompt:
“Access other apps and services on this device”

If you previously selected Block, reset the permission by following these steps:

Chrome Browser

1. Open a new window in Chrome and go to the Dell support website.
2.  Select the Security Status symbol next to the web address.
3. Select the slider button next to Apps on device to shift the button to the right and turn the slider blue.
   
   
   Note: Clicking the Reset permissions button will reset ALL permissions in this section.

Microsoft Edge

1. Open a new window in Edge and go to the Dell support website.
2.  Select the Security Status symbol next to the web address.
3. Under Permissions for this site, select the dropdown next to Local network access.
   
4. Select Allow to enable local network access.

For other browsers, refer to your browser support documentation.

Regardless of browser, if you have SupportAssist installed on your device there is no need to reinstall the application.

Managing local network access permissions for Administrators

Administrators can control this feature using Chrome's enterprise policies:

• Use the LocalNetworkAccessAllowedForUrls policy to allow access for specific sites.
• Use the LocalNetworkAccessBlockedForUrls policy to block access for specific sites.
• Setting the policy value to '*' allows local network access on all URLs, mimicking the behavior before the restriction was fully implemented.
