title: deploying rails to heroku - unauthorized public key access
body: <p>So I'm trying to deploy my app to heroku but it keeps giving me this error whenever I push to master:</p>
  
  <p><code>!  Your key with fingerprint cb:e1:5c:31:cd:6b:78:6e:30:ff:eb:11:e2:4b:2e:b3 is not authorized to access smooth-mountain-8970.</code></p>
  
  <p>I tried everything from generating new ssh keys to deleting everything and replacing the files. I even created a different username and tried uploading, but it keep giving me this error thinking that I want to upload to smooth-mountain when in fact, my app name is NOT smooth-mountain. Do you guys know what the problem might be? </p>
  
  <p>Thanks. </p>
