问题
I have got a server which points to AWS ec2. - domain:-hometriangle.com
And the Images are getting served from AWS CloudFront with SSL which internally points to ec2.: domain:-static.hometriangle.com
Both Pinterest and Twitter are not able to fetch images. Whereas Facebook and Google are handling it well.
Twitter errors:I get following logs in Card Validator
> INFO: Page fetched successfully INFO: 22 metatags were found INFO:
> twitter:card = gallery tag found ERROR: Internal Proxy Image Service
> Error (twitter:image0) ERROR: Internal Proxy Image Service Error
> (twitter:image1) ERROR: Internal Proxy Image Service Error
> (twitter:image2) ERROR: Internal Proxy Image Service Error

Pinterest Errors: Oops Unable to fetch/ Something is wrong.
My robots.txt for cdn url looks like this

If I replace cloudfront urls with direct urls, Images are getting fetched. What could be the issue?

I've also encountered this issue with Pinterest. Some experimenting revealed that Pinterest has issues with SNI (Server Name Indication) -based SSL connections.
To demonstrate this, I set up 2 new Cloudfront distributions. Both had SSL enabled, one used the default Cloudfront certificate and the other used my custom certificate and required SNI. I don't have the budget to try the $600/month SSL option so I can't comment on that.
Both distributions were accessible via the browser using the Cloudfront URL over SSL.
Pinterest was able to pin from the non-SNI distribution but unable to pin from the SNI-based distribution.
I sent Pinterest a support request over a week ago but all I got was automated responses. Bom-bom.
Here's the wiki on SNI. All major modern browsers support it but I guess whatever Pinterest is written in does not. http://en.wikipedia.org/wiki/Server_Name_Indication
