This article addresses the issue where the remote certificate is invalid according to the validation procedure in Patch Manager.


All Patch Manager versions


This error occurs when the SSL certificate is missing or mismatched between Patch Manager and a WSUS server using SSL.


When using SSL in WSUS, the certificate will need to be imported into Patch Manager as well.  Patch Manager handles this automatically if the SSL options are enabled when adding a WSUS server.


If the WSUS already exists, it will need to be re-added to trigger the import again.  This will remove the existing WSUS Inventory information associated with the WSUS server, but once re-added the next Inventory task should repopulate the report.  This step is necessary for Patch Manager to appropriately import the SSL certificate.


To remove an existing WSUS server:

  1. Select Update Services. 
  2. Select the old WSUS server in the middle Update Services pane.
  3. In the Actions menu, select Delete.
  4. Click OK to purge the Inventory data. 


To re-add the WSUS server:

  1. From the Update Services view as above, select Add or Configure WSUS Server from the Actions menu.
  2. Enter the WSUS hostname and click Resolve.
  3. Specify the WSUS port (443 is default for SSL on 2008, 8531 is default for SSL in 2012).
  4. Select the Operating System Version if it is blank.
  5. Click Save.
  6. Patch Manager will import the updated SSL certificate.
