title: Teamcity deploy to Heroku
body: <p>I am trying to deploy an app from git on teamcity to Heroku but I keep getting this:</p>
  
  <pre><code>Step 2/2: Deploy to Heroku (Command Line)
  [22:48:15]: [Step 2/2] Starting: git push git@heroku.com:HEROKUPROJECTNAME.git master
  [22:48:15]: [Step 2/2] in directory: /home/teamcity/TeamCity/buildAgent/work/c5d161aeb8cf26ed
  [22:48:16]: [Step 2/2] Host key verification failed.
  [22:48:16]: [Step 2/2] fatal: The remote end hung up unexpectedly
  [22:48:16]: [Step 2/2] Process exited with code 128
  [22:48:16]: [Step 2/2] Step Deploy to Heroku (Command Line) failed
  </code></pre>
  
  <p>I do have the keys set up. The public key is set up at heroku. This is what my ssh config file looks like:</p>
  
  <pre><code># Heroku forproject
  Host heroku.com
  HostName heroku.com
  User teamcity
  IdentitiesOnly yes
  IdentityFile /home/teamcity/.ssh/teamcity_project_rsa
  </code></pre>
  
  <p>Do you guys have any ideas or suggestions?</p>
