Problem With Facebook Shares -- Could Not Resolve Hostname

Hello, I'm having a problem with Facebook shares from my flexi toolbar field in flexi items on worldnewstrust.com. No image or text appears in Facebook shares. Debugging the item urls helped at first, but now debugging is not fixing the problem. All the metadata looks good. This is from Facebook debugger:

Warnings That Should Be Fixed

• Can't Download
  Could not resolve the hostname into a valid IP address.

Facebook shares from my JomSocial activity feeds on the same site are having no problem.

The Facebook World News Trust page (that I am trying to share to) shows no restrictions or violations.

This issue is very similar to one I had 12 years ago:

Any suggestions? Please advise. -Francis

  Hi, Micker.

Here's a screenshot of a Facebook share of an article from worldnewstrust.com to the World News Trust Facebook page. You can see that neither the photo nor the headline or summary text appear as they should. Part of the problem is that this is intermittent. Sometimes the shares work ok. We don't know why lately they usually don't work, even after processing through the Facebook debugger.
   
Joomla version 5.1.2
Flexicontent version 4.2.1

(There's only one attachment. I am not able to remove the "Attachment not found" comments.

However, I'm not sure this is a FLEXIContent issue:

It seems to be related to your hosting setup.

yes i think

iamrobert, Micker, Yes. We activated Cloudflare CDN (free version) for our nameservers. It improved site performance, solved the Facebook share issue and reduced bot traffic. Also, site Google Adsense ads are now loading properly on Chrome.

Thanks for pointing us in the right direction to resolve this.

Cheers, Francis
