Can't get Featured Image on Facebook.

My user attaches a Featured Image to a post & publishes. SmartCrawler Pro (SCP) should pick up that image in the OG & use it for Facebook. It does not. Have also been using the FB Dev Debug tool to re-scrape, not working.

Example: https://phat****

Getting the following error.

“Error while downloading https://phat**** with HTTP response code: 404”

Please check and help.
