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****.phatafrica.com/press-releases/award-winning-brazilian-singer-luedji-luna-in-concert/

Getting the following error.

"Error while downloading https://phat****.phatafrica.com/wp-content/uploads/2018/12/LUEDJI-LUNA-Instagram.png with HTTP response code: 404"

Please check and help.
