Rails image disappears with error: Failed to load resource: net::ERR_CONTENT_LENGTH_MISMATCH

Question

Essentially my problem is that a page loads fine and looks normal. After about 30 seconds it suddenly disappears.

Here's the server log before the error (as loading the page):

Started GET "/" for 127.0.0.1 at 2014-03-11 23:53:30 -0400
Processing by PagesController#home as HTML
  Rendered pages/home.html.erb within layouts/application (0.7ms)
  Rendered layouts/_head.erb (3.3ms)
  Rendered layouts/_header.erb (0.9ms)
  Rendered layouts/_footer.erb (0.2ms)
Completed 200 OK in 11ms (Views: 10.5ms)

Started GET "/assets/favicon.ico" for 127.0.0.1 at 2014-03-11 23:53:30 -0400

Started GET "/assets/application.css?body=1" for 127.0.0.1 at 2014-03-11 23:53:30 -0400

Started GET "/assets/home.css?body=1" for 127.0.0.1 at 2014-03-11 23:53:30 -0400

Started GET "/assets/taylor.jpg" for 127.0.0.1 at 2014-03-11 23:53:30 -0400

Started GET "/assets/wide.jpg" for 127.0.0.1 at 2014-03-11 23:53:30 -0400

Started GET "/assets/enchanted_large.png" for 127.0.0.1 at 2014-03-11 23:53:30 -0400

Started GET "/assets/sad.jpg" for 127.0.0.1 at 2014-03-11 23:53:30 -0400

And then suddenly the image dissappears with the client side error (seen in Chrome's dev console):

Failed to load resource: net::ERR_CONTENT_LENGTH_MISMATCH
  http://localhost:3000/assets/taylor.jpg

And the only addition to the log is:

Started GET "/assets/favicon.ico" for 127.0.0.1 at 2014-03-11 23:54:00 -0400

During the 30 seconds of it looking good, chrome has a loading symbol where the favicon goes

My html is rather simple at this point:

<div class="home-images">
  <%= image_tag "taylor.jpg", class: "home-image" %>
  <%= image_tag "wide.jpg", class: "home-image hide" %>
  <%= image_tag "sad.jpg", class: "home-image hide" %>
</div>

I even took out my javascript completely. I tried removing turbolinks by itself too. It only happens to one image. And I have no idea why...

When I switched the html, it was the same image (taylor) that gave the error:

<div class="home-images">
  <%= image_tag "wide.jpg", class: "home-image" %>
  <%= image_tag "taylor.jpg", class: "home-image hide" %>
  <%= image_tag "sad.jpg", class: "home-image hide" %>
</div>

All my images are located in my app/assets/images folder

My header looks like this:

<head>
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Enchanting Events and Design</title>
  <%= favicon_link_tag       "favicon.ico" %>
  <%= stylesheet_link_tag  "application" %>
  <%= javascript_include_tag  "application" %>
  <%= csrf_meta_tags %>
</head>
Was it helpful?

Solution 2

I had this issue when I replaced an image using the mv command. This left the timestamp untouched, so it broke the asset caching. A simple touch of the affected file fixed it.

OTHER TIPS

Ran into the same issue when I edited my image size.

None of the above solutions worked for me, but rake tmp:clear did!

Try "rake assets:clean" and rebuild your asset(if you need). I got working by this magic.

This may be a symptom of another problem with nginx. Please see this article:

Rails image disappears with error: Failed to load resource: net::ERR_CONTENT_LENGTH_MISMATCH

I saw the same issue as you, and it turned out to be an nginx permission issue with the underlying cache directory which also caused the problem to be somewhat intermittent.
