Upgrade Rundeck Community 4.9 (WinRM not Working)

Hello
Since upgrade Rundeck community to v4.9 I have a problem with WinRM plugin.
All Windows Servers are concerned.

I have the following error:
1=Dispatch failed on 1 nodes: [xxxxxxx: Unknown: com.dtolabs.rundeck.core.CoreException

Do you have an idea.

Thanks in advance for your help

For Information . it’s working in V4.7
