ansible SSH connection fail : <p>I'm trying to run ansible role on multiple servers, but i get an error:</p>

<blockquote>
  <p>fatal: [192.168.0.10]: UNREACHABLE! => {"changed": false, "msg":
  "Failed to connect to the host via ssh.", "unreachable": true}</p>
</blockquote>

<p>My /etc/ansible/hosts file looks like this:</p>

<pre><code>192.168.0.10 ansible_sudo_pass='passphrase' ansible_ssh_user=user
192.168.0.11 ansible_sudo_pass='passphrase' ansible_ssh_user=user
192.168.0.12 ansible_sudo_pass='passphrase' ansible_ssh_user=user
</code></pre>

<p>I have no idea what's going on - everything looks fine - I can login via SSH, but ansible ping returns the same error.</p>

<p>The log from verbose execution:</p>

<blockquote>
  <p>&lt;192.168.0.10> ESTABLISH SSH CONNECTION FOR USER: user &lt;192.168.0.10>

<p>Can you help me somehow? If I have to use ansible in local mode (-c local), then it's useless.</p>

<p>I've tried to delete ansible_sudo_pass and ansible_ssh_user, but it did'nt help.</p>
