title: SFTP connection returns "Auth cancel"
body: <p>I'm using PhpStorm 2016.2.1, Windows 10. I'm trying to connect to remote host via SFTP. Credentials are correct. When I'm testing the connection, I have this error:</p>
  
  <pre><code>Connection to 'foobar.com' failed.
  Auth cancel
  </code></pre>
  
  <p>I can connect using FileZilla. I've cleared PhpStorm known_hosts. On different machines (PC, Mac) connection works perfect. Tried key pair auth, disable antivirus/firewall - same error. Traditional FTP connection on port 21 works perfect.</p>
  
  <p>I have no idea what is wrong. Any ideas?</p>
