SCP not working with windows to windows file transfer

Hi

we want to achieve the Jenkins pipeline in cross IP environment(same server domain but different IP)  I am trying to copy the shell script file from one windows server to another windows server (through shell script), after successful copy of file we want to execute that copied shell script file on target server(where we copied the file). when we trying to implement this we are facing the following challenges:-

1. How we can authenticate the target server because RSA_private_key and Public_key exchange method is not working?
2. When we try to implement this through scp and ssh configuration through plugin and openssh we are getting the following error:

If you need any further clarification kindly let me know.

It will be great if you can help me on the above error.

Thanks!
