Microsoft Defender Application Guard can't access the Internet

Question

Microsoft Defender Application Guard can't access the Internet

Darren Wray 15

Hi

On my home PC running Windows 10 Pro, Microsoft Edge can't access the Internet / open any web pages in an Application Guard window.

When I enter a URL there's a delay of about one minute then it displays the message:

"Hmmm... can't reach this page. ERR_CONNECTION_TIMED_OUT"

I am running Application Guard in standalone mode. I am not using a VPN or proxy server.

I don't know if this is related to the problem but in the Application Guard window settings it says: "Your browser is managed by your organisation" even though I am using my home network.

I have not been able to get this feature to work since I enabled it.

I have followed the setup instructions to the best of my ability. I have enabled the optional features Hyper-V and Microsoft Defender Application Guard and I have enabled virtualisation and hyperthreading in the BIOS.

I have a stable Internet connection and I can access the Internet using any browser including Microsoft Edge. The problem only occurs in a Microsoft Edge Application Guard window.

I am using Windows 10 Pro version 22H2.

Thanks!

Hi @Darren Wray ,

"Your browser is managed by your organization" this means is that the settings for the Edge browser are being managed via Group Policy by your system administrator.
Please enter "edge://policy/" in Edge, then please share us the screenshot for the policies that are applied.

@Darren Wray Any updates? Have you been able to solve this issue. I have a similar issue https://learn.microsoft.com/en-us/answers/questions/1399654/internet-traffic-blocked-when-trying-to-surf-in-ed and have tried anything from allowing traffic via setting rules in my Trellix firewall program but to no avail? Let me know how you solved it.

Everything was working well until I updated the edge browser.

I was able to resolve this issue by uninstalling application guard and reinstalling. Make sure you restart.
