Windows quick assist blocked by Zscaler

[loueystrong (louey bencheikh lehocine)]

Hi,

We are deploying Zscaler in our company, and we just noticed that the Windows quick assist doesn’t work with ZIA enabled. There is no URL to authorise as it is a host-to-host application.

What can I do to authorise this application ?

Thank’s in advance for your help.

Best resgards,

Hi,

As per microsoft article: https://docs.microsoft.com/fr-fr/microsoft-365/managed-desktop/get-ready/network?view=o365-worldwide

Here are the URLs to allow:

Quick Assist

remoteassistance.support.services.microsoft.com
relay.support.services.microsoft.com
channelwebsdks.azureedge.net
web.vortex.data.microsoft.com
gateway.channelservices.microsoft.com
*.lync.com

Hi Charles,

I have whitelisted and exempted those URL’s from SSL inspection but Quick Assist still doesn’t work.

There is anything I can do for that ?

If it still necessary you can, add exclusions to the PAC file or add to exclusions Charles URLs (above) from SSL inspection, but change the bloody relay.microsoft … to wildcard

relay.support.services.microsoft.com
to this one support.services.microsoft.com
