Fix ERR_SPDY_PROTOCOL_ERROR in Chrome

If you are getting ERR_SPDY_PROTOCOL_ERROR page in Google Chrome browser when you visit Google sites like Reddit, Facebook, YouTube, Wikipedia and Tumbler, etc, then Here’s the solution of error. We have 2 web applications deployed from the machine, and both were running perfectly fine. Recently, we deployed one of the applications with changes to cached assets. Once the deploy completed, we immediately got the ERR_SPDY_PROTOCOL_ERROR from Chrome. Interestingly enough, it was receiving an HTTP 200 and if you navigated to the asset directly, Chrome would render the asset. However, loading the asset on a page would cause it to fail.

Interstingly enough, the other web application was perfectly fine. Investigating the net internals on Chrome, we discovered the server was closing the connection. After several hours, we determined that it was because our nginx server had run out drive space. I don’t know why that would cause the assets to load properly when you navigate to them directly, but fail when you load a page, but clearing out space instantly fixed the problem.
