title: Reason for Cache Manifest: Application Cache Error event: Resource fetch failed (2)
body: <p>My manifest file was working fine until this morning and I now keep getting the following error in chrome Version 36.0.1985.143 m</p>
  
  <pre><code>Creating Application Cache with manifest https://localhost/static/app/cache.manifest dashboard:1
  Application Cache Checking event dashboard:1
  Application Cache Downloading event dashboard:1
  Application Cache Progress event (0 of 192) https://localhost/static/app/images/ui-icons_454545_256x240.png dashboard:1
  Application Cache Error event: Resource fetch failed (2) https://localhost/static/app/images/ui-icons_454545_256x240.png
  </code></pre>
  
  <p>The resource is there when i follow through the link. But i can not find anywhere that details what the (2) means (seen lots for -1 but nothing for (2)) . I have a valid certificate for https as this was one of my pitfalls when first dealing with the cache manifest so do not believe that this is the issue.</p>
  
  <p>Here is my manifest (it is generated by grunt and seems to be valid)</p>

  <p>So my question is does anyone know what the error means and how it can be fixed?</p>
  
  <p>Edit: This problem disappeared on it's own after a day but I do not know what caused it or what I might have done to fix it the only action i did do was clear my flags in chrome (experimental features) but this did not have an immediate effect to remove the error</p>
  
  <p>Here are some other facts about this error</p>
  
  <ul>
  <li>Other developers with the same code did not see this error (same version of chrome) (I know this makes for a bad SO question if it is not reproducible but I have no idea what the error even means hence the main reason for asking)</li>
  <li>This happened on both the development version and production version (development version using Apache and production using nginx)</li>
  <li>This did not happen to other websites that I know to use appcache (deezer.com)</li>
  </ul>
  
  <p>edit: as of 04/09/2017 i still have never found the root cause for this error or seen it again actually</p>
