Google not pulling my favicon

[FedeEinhorn]

Several sites use Google favicon to load favicons instead of loading it from the Website itself.

Our favicon is not being pulled from our site correctly, instead it shows the default "world" image.

https://plus.google.com/_/favicon?domain=www.example.com

Is the address to pull a favicon. When I post on G+ or see other sites that use that service to pull favicons ours isn't displaying, despite it shows up in Chrome, Firefox, IE, etc and we have the correct meta in all pages of our site.

Any idea why is this happening? Or how to "ping" Google to update that?

Have you tried naming your file favicon.ico (using an ico generator), placing it in the root directory of your site, and making sure it's accessible without SSL (i.e., http://www.example.com/favicon.ico)?

The favicon.ico is named like that, in the root and accessible both with SSL and without.

Google used to show it, but a few weeks ago I noticed the issue while I was posting a link to my site in G+.

I found the problem myself.

My site is under cloudflare, and apparently they were blocking the IP requesting the favicon file.

As a fix, I added the favicon to the CDN (which does not go through cloudflare) and the issue is now fixed.
