Windows Server 2025 Servermanager: Refresh failed

Error servername : Configuration refresh failed with the following error: The WS-Management service cannot process the request. The computed response packet size (514948) exceeds the maximum envelope size that is allowed (512000).

Another error that could have easily been avoided by choosing a better default value. The solution: Open Powershell as Administrator and type:

PS Set-WSManInstance -ResourceURI winrm/config -ValueSet @{MaxEnvelopeSizekb = "600"}
