Windows Defender Application Guard doesn't work properly in domain environment .Hangs and cant connect to internet

Question

I am trying to reduce attack surfaces via browsers by activating WADG -> Edge Chromium Sandbox Mode. I tested this on a standalone without enterprise configurations and it worked perfectly. I also tried to activate and test it on Clients in the enterprise - domain environment but encountered a few issues. 1. The Sandbox Container crashes after it is left running for a while. 2. No Internet connection (see attached screenshot) via the container is possible even after forcing direct proxy configurations and testing a few policies like network isolation etc. I heard the usual culprits in the domain environment are 1. The Windows Firewall blocking the App or traffic 2. Mcafee / Antivirus Firewall Settings could also be blocking settings. In case anyone some experience with this pls share tips no how it was this solved or some troubleshooting tips will be very much appreciated. I already posted in the browser forum but i could get an opinion from here

Hi Sharkbone. I'm Greg, here to help you with this.

Please ask domain questions at our Sister forums for IT Professionals, Q&A forums here: https://docs.microsoft.com/en-US/answers/index.... ?
