Connect to Local Network Popup

❔ What’s Happening

When you open an internet page with one of our framework components in a browser, you may see a message like this:

“This site wants to look for and connect to any device on your local network.”

This message can look confusing, but it’s expected and completely safe when it comes from a site using our framework components like ADM and/or CM.

Chrome local network access prompt asking for permission

Example of the prompt you may see when opening the site in Chrome.

Why The Browser Shows This Message

Modern browsers, like Google Chrome and Microsoft Edge, are designed to protect you from websites that might try to connect to devices in your home or office network — for example, printers, scanners, or internal tools.

Because our framework components communicate with local REST services running on your company network, the browser asks for confirmation the first time. It’s simply checking that you trust this site communicating with your local network.

Why You Can Safely Allow It

Our components need to talk to local REST services in order to work properly.
For example, this connection allows our website components to:

Read or send data to software running elsewhere on your network (e.g.: SAP, CRM, a database, ...)
Perform secure operations that are not possible directly through the internet

This communication stays entirely between your computer and the REST services — nothing is exposed publicly.

How IT Can Apply the Chrome Policy to Avoid the Prompt

If your organization manages devices with Chrome, IT can pre-approve sites so users never see the “Local Network Access” prompt. This is done using a Chrome Group Policy called:

LocalNetworkAccessAllowedForUrls

What This Policy Does

Allows specific public websites (like the company sites) to access local network services
Bypasses the one-time prompt in Chrome for end-users
Only works on managed devices (Windows, macOS, Linux, ChromeOS)

How to Configure via Windows Group Policy

Follow the article about Chrome browser policies and install the ADMX template (direct link)
Navigate to Start > Run: gpedit.msc. (Or run gpedit.msc in your terminal)
Find Allow sites to make requests to local network endpoints.
Enable the policy and add the sites containing our framework components, for example: https://www.company.net, https://portal.company.net, https://company.sharepoint.com, ...
Once the policy is pushed to the client, users will no longer see the prompt for those sites

Example of the group policy editor

How to Configure via the Register (also for Microsoft Edge)

For Chrome: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome\LocalNetworkAccessAllowedForUrls
For Edge: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Edge\LocalNetworkAccessAllowedForUrls

Example of the registry setting for Chrome and Edge

⚠️ Notes for IT

Only whitelist trusted websites containing our framework components
Don't use wildcards like * — browsers will ignore them for private network access

When you see the prompt in Chrome:

Verify that the website shown is a trusted site used by the company (e.g. https://app1.company.com or https://portal.company.net or even https://company.sharepoint.com).
Click Allow to grant access.

User clicking Allow in Chrome local network access prompt

Click “Allow” once to continue — Chrome will remember your choice.

That’s it!
After you approve it once, Chrome will remember your choice, and you won’t be asked again for that site.

⚙️ If You Click “Block” by Accident

If you accidentally block the request, the local connection will not work correctly.
You can fix it by:

Clicking the tune icon in the Chrome address bar.
Finding Local network access and switching it to Allow.
Refreshing the page.

You can later change the permission under “Site settings” if needed.

📋 Summary

Step	What Happens	What To Do
You open the site	Chrome asks if it can access your local network	Click Allow
Why?	Chrome protects you from untrusted sites	Our components are trusted
After approval	You won’t be asked again	Chrome remembers your choice

🔐 Important Notes

This permission only allows communication between your computer and the local network
Your data and credentials remain protected
You should never allow local access for unknown or untrusted websites

More information about this change can be found in the W3C Community Group Report and in chrome's developer blog.
