Troubleshooting HTTP Status 404 Errors in Patch Manager

Patch Manager returns the following error after it tries unsuccessfully to connect to a WSUS server.

Error Message: The request failed with HTTP status 404: Not Found.



Patch Manager



Patch Manager is configured to connect to the WSUS server on a different port than the one on which the WSUS server is installed. This is a common issue in environments that use a port other than 80 for WSUS.

Note: WSUS version 6 (installed on Windows Server 2012) installs to port 8530 by default.


Update the WSUS configuration in Patch Manager to reflect the correct port.

To change the port assigned to a WSUS server in Patch Manager:

  1. In the left pane of the Patch Manager console, expand Enterprise, and then select Update Services.
  2. In the Add or Modify WSUS Server window, select the WSUS server from the Server Name menu.
  3. Modify the port assignment in the Port field.
  4. Click Test Connection.
  5. If the test fails, double check the port value and then try the test again.
  6. After a successful test, click Save.
