Jenkins ssh agent plugin is getting stacked, No error, no timeout issue

Question

I installed jenkins ssh agent plugin. I created ssh private key on the linux server(using ssh-keygen -t rsa command) I am trying to connect. Then under jenkins credintials added SSH Username with private key with all required fields. In jenkinsfile added simple command to run over ssh:

pipeline {
   agent any
   stages {
       stage('---doingsomething---') {
            steps {
                sshagent (credentials: ['jbowner-195']) {
                    sh 'ssh -o StrictHostKeyChecking=no -l jbowner 10.10.23.195 uname -a'
                }
            }
       }

   }
}

When I press build button process is starting and never ending. No error, no timeout issue. Here is piece of output on which jenkins stacks

[Pipeline] }
[Pipeline] // stage
[Pipeline] withEnv
[Pipeline] {
[Pipeline] stage
[Pipeline] { (---echoing---)
[Pipeline] sshagent
[ssh-agent] Using credentials jbowner (jbowner 10.10.23.195)

[ssh-agent] Started.
[Pipeline] {
[Pipeline] sh
+ ssh -o StrictHostKeyChecking=no -l jbowner 10.10.23.195 uname -a

any ideas?

Jenkins ssh plugin didn't work for me. My solution is

generate rsa keys on source machine using ssh-keygen -t rsa
ssh-copy-id username@destination_ip. Then enter destination password. This will add as destination ip as a known host and adds source key on the destination machine as a authorized key.

then instead of using jenkins ssh agent I used standard ssh command like this.

pipeline {
   agent any
   stages {
       stage('---echoing---') {
            steps {
                sh 'ssh -o StrictHostKeyChecking=no jbowner@10.10.23.195 uptime'
            }
       }

   }
}

This is working because servers have been trusting each other using ssh key
