jenkins node ssh-connection fails

I try to connect a VM(Windows 10) as a node in jenkins with ssh. But after some lines occurs the following error:

[10/11/18 11:45:10] [SSH] Starting agent process: cd "C:\jenkins" && java  -jar remoting.jar -workDir C:\jenkins

As noted on https://issues.jenkins-ci.org/browse/JENKINS-42856 this could be a known issue. Can you see if the below workaround mentioned on the above JENKINS bug helps ?

I have a similar problem with the channel being terminated too early. I was able to circumvent it using the following SSH prefix and postfix commands:

Prefix: powershell -Command "cd C:\jenkins ; java -jar slave.jar" ; exit 0 ; rem '

Postfix: '
