Fetcher cannot resolve the address


I’m trying to validate http://lukfook.hylinkgz.cn/loveisbeautyhk/share.php?type=http%3A%2F%2Flukfook.hylinkgz.cn%2Floveisbeautyhk%2Fniceimgs%2Fb4d13d896fe3e34fcdfe28230d7ff218a.jpg this link, and the validator return ERROR: Fetching the page failed because the fetcher cannot resolve the address. Could anyone help to see what is wrong? I’m running a CDN as the front-end and the CDN guy wants to know the fetcher’s ip or the CDN node the fetcher is using? Thanks
