WinGet source update cancels for winget and winget-font with 0x80072EFE / 0x80072EFF while direct CDN access works #6586

Brief description of your issue

WinGet source refresh is failing system-wide. msstore updates successfully, but both winget and winget-font return Cancelled. The issue persists after source resets, App Installer re-registration, DISM/SFC repairs, an in-place Windows 11 repair install, and testing on a completely fresh local administrator account.

Direct access to the same WinGet CDN endpoints works normally outside WinGet. curl returns HTTP 200 and a direct WinHTTP request to the same URL also returns 200. Verbose WinGet logs instead show connection reset / terminated errors with 0x80072EFF and 0x80072EFE.

Steps to reproduce

Open Command Prompt or Terminal.
Run:
winget source update
Observe:
Updating source: msstore...
Done
Updating source: winget...
Cancelled
Updating source: winget-font...
Cancelled
Run:
winget source reset --force
Then run a normal search command, for example:
winget search powertoys
WinGet fails to open the source.

The same behavior occurs on a completely fresh local administrator account.

Expected behavior

winget source update should successfully refresh the winget and winget-font sources, and normal winget search commands should be able to open and query those sources.

Actual behavior

msstore updates successfully, but winget and winget-font both return Cancelled.

After resetting the sources, WinGet still fails to open them.

Verbose logs show failures while retrieving headers from:

https://cdn.winget.microsoft.com/cache/source2.msix

with errors including:

0x80072EFF
0x80072EFE

indicating that the connection was reset or terminated abnormally.

Direct requests to the same CDN URL succeed outside WinGet, including curl and a direct WinHTTP request returning HTTP 200.
