Microsoft Defender Application Guard can't access the Internet

Darren Wray 0 Reputation points


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.
