Am i the only one…Windows Sandbox has no Internet connectivity on my machine. Using Avast v 19.5 Internet Security. When i uninstall Avast the Windows Sandbox has internet. What gives?
EDIT: Well i just worked out that the Avast Firewall is blocking the Windows Sandbox. The problem is the module itself. It has nothing to do with a program that i may have blocked because resetting to default and rebooting still blocks the Sandbox. Only when i disable the firewall module the problem is resolved. I suspect it has something to do with the pop up about Public or Private Network issue.
Yes it is set to private but Im one of those people who keeps getting the New network profile popup at startup and when i go to slide it to private nothing happens. It is non responsive. However when i check my firewall settings, the current profile is set to Private. Avast team need to do some work in this area.
This has only started to happen since i upgraded to Windows 1903.
Hi bob3160. In my case, the Windows Sandbox does load normally except in the Sandbox my network icon has an “X” in it and there is no internet connection unless as stated i disable the avast Firewall.
But in your case you dont even seem to be able to start Windows sandbox at all. So do you have VMWare Workstation installed? If so were you getting this error message (See attachment)?
A recommended “fix” for this was
Open cmd as an administrator, run below command.
bcdedit /set hypervisorlaunchtype off
After that restart your host.
On my machine this did fix the VMW error but as a side effect caused Windows sandbox to freeze at the logo screen…so i had to restore to a previous image in order to reverse the change.
I dont have any other suggestions for you. Hope this has helped or given you ideas on how to resolve your issue.
Other more general responses from google talked about corrupted files and running Scannow command to check system files. Turning the Sandbox feature on and off between reboots may also solve your issue. Other than these suggestions i’ve got nothing. Perhaps someone with more knowledge can help you…
I’ve already tried all the suggestions without success. If you check the Microsoft help site, you’ll also see that it’s a problem for which MS doesn’t yet have an answer.
Well… the new v19.6 upd has done nothing to resolve this issue for me. All is as it was before…
Edit: The network profile is still popping up on my PC. First reboot all good, now subsequent reboots the network profile is popping up. It looks to me like no work was done regarding this bug.
Sorry mchain, but i’ll have to disagree. I’ve already established in the OP that disabling the firewall restores network access in Windows Sandbox (you have to restart the Sandbox). And since network profiles is part of the firewall …you see where I’m going with this…
I’m not aware of any setting to disable the network profiling in avast. It looks integrated into the Avast firewall itself. Since this profiling issue reared its ugly head after the v1903 update, it stands to reason that Avast need to iron out the bugs in this module.
Edit: The attachment you uploaded says v18.8. Those settings dont exist in v19.6…unless i’m mistaken?
Edit2: After some hunting around i found an obscure setting called “Open old settings” located under MENU>SETTINGS>GENERAL>TROUBLESHOOTING. Hidden at the bottom is the “Open old Settings” option. Now you go to COMPONENTS>FIREWALL>CUSTOMISE. Here you’ll see the NETWORK PROFILES settings…phew! Finally, now were getting somewhere. So I untick “enable automatic profile switching”. Close all the windows. Open all the windows to see if it stuck and drum roll…still remains ticked. It seems that us mere mortals have no power in resolving this.
I think that this can only be resolved by MS or Avast (depending where the issue lies).
FYI, I only have to disable the Firewall component of Avast for the internet access to be available to the Windows sandbox. This way i still have AV protection.
That doesn’t work for everyone. I use the free version so there is no firewall. I’m using the firewall that’s part of windows 10.
I still can’t use the windows sandbox feature.
For anyone who wants to know, I’ve solved my issue with Windows sandbox having no internet connection. Upon reading the replies of the new v19.7 release, someone mentioned an “internet connection sharing mode” setting located in the firewall settings. I went in and enabled it. Started Windows Sandbox and wholla, internet working!
I found this solution on the AVG forum and can confirm that it works in avast too, however there is a caveat in the FAQs regarding this to the effect that it should be disabled when not required and I’m happy to go along with that and only enable it when using Windows sandbox.
Furthermore, I have just started using avast SecureLine VPN, and now find that this also has to be turned off to be able to use Windows sandbox.
I noticed this is still a problem in 2021. Windows 10 (21H1) Sandbox stopped working when I installed avast. Once I enabled “Internet Connection Sharing Mode” it started working again.
