title: Appcenter pipeline was working fine, but now not building
body: <p>My pipeline on appcenter was working fine.
  Now I tried to do a push, but is failing with:</p>
  
  <pre><code>##[command]git fetch --tags --prune --progress --no-recurse-submodules origin
  remote: Invalid username or password
  fatal: Authentication failed for 'https://***:***@bitbucket.org/company/react-native-proj.git/'
  ##[error]Git fetch failed with exit code: 128
  </code></pre>
  
  <p>how to fix this?
  I have checked and says I have to check for disabled web hooks

  <p>but I have no "disabled" web hooks on bitbucket?</p>
  
  <p>How to fix it? what was the cause?</p>
  
  <p>Thanks!</p>
