Issue Web Deploy Publishing fails

Paul Hermans

Basic Pleskian
We have a clean server installation with Windows Server 2019 and Plesk Obsidian 18.0.20

When testing a Web Deploy Publish in Visual Studio 2019 it fails with following error:

An error occurred when the request was processed on the remote computer.
Unable to perform the operation. Please contact your server administrator to check authorization and delegation settings.

The connection works because I see the file "App_Offline.htm" is created in the httpdocs directory.

When I add the Plesk user to the "Administrators" group, deployment is successful, so it clearly has something to do with permissions/authorization/delegation just like the error is suggesting.

Event Viewer Logs:

A tracing deployment agent exception occurred that was propagated to the client. Request ID '7663ab39-a633-4122-996b-6863d8bab392'. Request Timestamp: '19-11-2019 14:08:09'. Error Details:
Microsoft.Web.Delegation.DeploymentAuthorizationException: Not able to log on the user '.\WDeployConfigWriter'. ---> System.Runtime.InteropServices.COMException: The user name or password is incorrect. (Exception from HRESULT: 0x8007052E)

Does anybody know how to fix this?

FIX:

Step 1:
Configure new passwords for users WDeployConfigWriter and WDeployAdmin

Step 2:
Go to IIS > Management Service Delegation
Set the new passwords on all 4 of the providers (right click > Edit > Run As user Set
 
This still is an issue today with a fresh installed Windows Server 2019 + Plesk Obsidian 18.0.24.

Plesk please have a look at this.
