Data from STW was Empty -outbound curl blocked
Posted by Brandon Elliott on 04 November 2014 12:40 PM

If you are not getting any previews / thumbnails displayed, even after checking the IP referrers list, your account limits, necessary upgrades, and your account status; then it could be that your web host is blocking outbound curl requests. You should open a ticket with them to ask if this is the case. If it is, then they need to whitelist the IP 173.208.100.210 (could change in the future). In some cases, the provider needed to whitelist the following IP instead: 173.208.100.211.

 

One known web host that blocks outbound curl is: Hosting2go

 

Note: This can also be caused by a "Shared IP block" (to prevent abuse by free accounts)
