title: I have been trying to deploy the war file built by jenkins into tomcat server through ansible playbook using jenkins pipeline
body: <blockquote>
    <p>PLAY [hemanth]</p>

    connect to the host via ssh: Host key verification failed.",

    <p>PLAY RECAP</p>

  <p>So when i'm building the job the error i get is like this, but when i tried pinging from my <strong>ansible</strong> server the connection seems to be fine and the playbooks are being deployed when i do it manually, what is that am I doing wrong? the ssh connection between the two servers seems to be totally fine i am able to login without any password authentication</p>
