Windows 10: Windows 10 Quick Assist will not work through my cloud web proxy

Hi,


I need to add Windows 10 Quick Assist to my cloud proxy Zscaler bypass list, of IP addresses or URLs to bypass. I have found that this proxy blocks Quick Assist, so desktops are not able to launch it. It launches and spins and spins and never connects. The minute I remove my proxy from Internet Explorer we use pac files...like wpad, it works.


I have tried searching for this information. I need to know what IP addresses or URLs Microsoft uses for Quick Assist. Does anyone know? I'm pretty sure it uses TCP 443, but I need to know the destination addresses.


Thanks

:)

 

Quick Assist not working

Good diagnostic step.

You've tried disabling 3rd party program startups, but there could be more things starting beyond those listed in the task manager startup list, if that's what you used.

Ideally you would have hands on access to both PCs... but that's not so. All credit to them for creating a new user account etc.

If you wished to disable more startups on the problem account you could use Autoruns (free from MS). But that seems asking a bit much of someone else remotely.

Of course, the problem could have nothing whatsoever to do with startups... you might want to check all services are default, for example, in particular those necessary for this.

Presumably it's not been blocked by the firewall:

- some unfinished discussion as to whether both accounts had to be MS accounts or not.

I found this:

Windows 10 Quick Assist: Helpful Remote Assistance App or Potential Vulnerability? — Steeves and Associates


https://4sysops.com/archives/remote-control-windows-10-with-quick-assist/

This gives useful detail on how it works. For example, it uses port 443, so you need to check that's not blocked.
It also indicates how to block it- so you can check that doesn't apply.

 

Quick Assist not working




I suppose another possibility might be that some related service is not configured correctly...

E.g. Tweaking.com's repair tool includes a repair to set services to default.

I suggest you look at affected PCs and check installed programs to see if there are any that are common only to those and not others, especially 3rd party security programs with firewalls.

I saw a note somewhere that there's no relevant group policy.

Is this idea relevant?
