Bug: WSUS Catalog import failures (0x80131509)

Error

• Error: 0x80131509
• If you use a proxy, be sure that it is the same proxy being used by your Windows Server Update Services (WSUS) server
  
• Your WSUS

Affected

• WSUS 5.0 (Windows Server 2016)

Solution

• After clicking on the “Import Updates…” option in the WSUS console, an Internet Explorer window will open on the following URL: http://catalog.update.microsoft.com/...&Protocol=1.20
• Before proceeding with importing the updates, change the “1.20” protocol value in the URL to the previous protocol value 1.8. The URL should look like this when you’re done: http://catalog.update.microsoft.com/...&Protocol=1.8
