SOLVED Content download failed in disconnected downstream WSUS server

[Anurag]

Hii
We are facing a typical problem.

we have one internet facing WSUS which download updates from Microsoft wsus. There we export updates and import updates to disconnected upstream WSUS server.
From this disconnected upstream server successfully downloaded updates to Sccm . But same updates failed to download into another downstream WSUS server

Software distribution log and event viewer log ID 364 showing same error
Content file download failed
Reason HTTP status 401: the requested resource requires user authentication

But clients can download updates(older updates, which are Allready downloaded) from downstream WSUS server

I can manually copy the file from upstream server to downstream server content location.once I copied one .cab file to downstream server content location from upstream server and retried download in WSUS console, it's showing successfully downloaded and ready for installation. Screen shot of event log and software distribution log attached.

You need to focus on this error - Reason HTTP status 401: the requested resource requires user authentication.
