title: SSH: Connection closed by remote server
body: <p>I am trying to ssh login to my remote server. But whenever i try to login through terminal using ssh command:</p>
  
  <pre><code>  ssh root@{ip_address}
  </code></pre>
  
  <p>I get error:</p>
  
  <pre><code> Connection closed by {ip_address}
  </code></pre>
  
  <p>I checked hosts deny and hosts allow, there is nothing in the file. I am not getting why it happening?</p>
  
  <p>It happened when i changed my workstation and key got changed. When i tried ssh login, it asked to add key and i entered yes and then it closed the connection.</p>
  
  <p>Is there any way to get connected with ssh again?</p>
  
  <p>Your help is appreciated.</p>
  
  <p>Thank you.</p>
  
  <p><strong>Edit:</strong></p>
  
  <p>Output of ssh -v -v -v -v root@{ip_address} is </p>
