avast! Firewall blocking conncetion to Windows Sandbox
« on: June 24, 2019, 03:38:48 PM »
Hello,

Since the Windows 10 1903 update, I find Windows Sandbox a really useful feature and use it extensively.

Only problem is, internet connection doesn't work. If I disable avast!, it does work, so the firewall is blocking it.

I tried adding the exe manually, but it didn't work, any suggestions?

Is your firewall in private or puplic mode?

Try private and reboot

It is in private mode, already tried rebooting after allowing WindowsSandbox.exe
