Delta Download giving timeout errors with April Unified Update Platform (UUP) update

Hi,

We are facing issue while downloading April/May 2023 cummulative update (UUP).
Issue is not specific to a device, its same for all Win11 22H2 clients.
Excerpts from Delta Download logs from different devices in different scenarios –

Correlation vector:Ax1DyMzeMki5IEVH.3.0.0.16.7.1.1.2.1.24, Sending Response status code:504 with reason = Gateway timeout

 

 

WUAHandler.log for all above says –

Unexpected HRESULT for downloading complete: 0x80d02002

 

 

As per our understanding Content Provider is slow, can this be the issue ?

Is there any setting we can do to have coordination in DO/DeltaDownload and ContentProvider.
We tried changing Max Download Bandwidth for DO client, made it very low but that didnt help.

We started facing this issue only with April/May UUP updates.

And this works fine in small, high bandwidth environments or if we download on just 2-3 machines.
Please help us to resolve this issue, its critical for our business.

 

Thanks and Regards
