Chrome - ERR_CACHE_MISS

Question

Does anybody know what the following Chrome error is?

Failed to load resource: net::ERR_CACHE_MISS

I have had a look online, but have not found

Answer 1

This is a known issue in Chrome and resolved in latest versions. Please refer https://bugs.chromium.org/p/chromium/issues/detail?id=942440 for more details.

Answer 2

This is an issue distinct to Chrome, but there are two paths you can take to fix it.

I noticed the error once I added this specific header to my PHP script.

header('Content-Type: application/json');

The error appears to be related to PHP sessions when sending response headers. So according to chromium bug report 424599, this was fixed and you can just update to a newer version of Chrome. But if for some reason you can't or don't want to update, the workaround would be to remove these response headers from your PHP script if possible (that's what I did because it wasn't required).

Answer 3

If you are using WebView in Android developing the problem is that you didn't add uses permission

<uses-permission android:name="android.permission.INTERNET" />

Answer 4

Yes, this is a current issue in Chrome. There is an issue report here.

The fix will appear in 40.x.y.z versions.

Until then? I don't think you can resolve the issue yourself. But you can ignore it. The shown error is only related to the dev tools and does not influence the behavior of your website. If you have any other problems they are not related to this error.
