Windows Updates Failing - WUfB

Question

Hey Everyone,

I've been plagued by a Windows update issue for some time now and I'm having trouble pinning it down.

Environment;

Azure AD only

Windows update for business enabled

NO Sccm client on the machines

Fresh out of the Autopilot process

A device that was new out of box went through Autopilot and when I went to test running updates on the device they failed and undid changes.

WUfB policies are successfully applying to the device.

Now I successfully updated by REMOVING the firewall config policy we have set up which was great UNTIL I tested reapplying the firewall policy and running the update again. After reapplying the firewall policy it successfully updated again. This has thrown me for a loop in trying to pin point where my issue is.

Has anyone ran into this before? Or could anyone office any input?

@Casey Throop Thanks for posting in our Q&A.
I saw a similar case there. This problem seems to be related to the firewall policy. So I suggest to create a new firewall policy with intune, to ensure that it will not block windows update urls, please refer to: https://learn.microsoft.com/en-us/windows/security/threat-protection/windows-firewall/create-windows-firewall-rules-in-intune
Also we can judge which steps have errors by looking at windowsupdatelogs :

Hope it can help.
