Local Network Access Permission: Browser Requirements for Ranger Remote (2026)

A number of browsers, including Chrome, Edge, Firefox are gradually introducing stricter permission requirements for web applications and websites that access the local network and user devices.

Going forward, users may be prompted by their browser to explicitly allow the website or web application to access the device. This permission is required for the application to communicate with the local Ranger Remote service.

Recommendation
We recommend users upgrade to the Chrome and Edge versions 147+ if they are already above version 142.

These new measures are being introduced broadly and affect any application that attempts to access a physical device connected to the user’s workstation through the local network. These changes do not indicate a security vulnerability. Instead, they introduce an additional security control for users.

Please consider the following regarding how this might affect the Ranger Remote service: 

1. Users should only be prompted once and the decision should persist between sessions for the application. To be able to communicate with the Ranger Remote service, the end user will need to select "Allow" for Apps on Device

Example prompt seen in Google Chrome and Microsoft Edge

2. Users can also change the Apps on Device permission, by clicking the site information icon.

Recommendation

For those that do not get prompted by their browsers, please check the site information icon on the left, to make sure a previous decision did not inadvertently disable the "Apps on Device" access

The tab might need to be restarted if the Apps on Device permission is changed via this option, before the new permissions take effect.

3. Your specific Policy or HTTP use (instead of HTTPS) can block browsers from prompting you:

1. It is important that there is no policy blocking you to receive the prompt.
   
1. You can verify the policies by Chrome://policy or Edge://policy section
   
2. Browsers might block prompting you about Apps on Device IF the browser communicates with the app over HTTP instead of HTTPS

4. Users can also permanently disable the new Local Network Access for WebSockets restriction measures by disabling the flag via the browsers settings. We don't recommend this as a permanent solution, but as a temporary work around until the browser update.
