Wordpress Blog article share on Facebook lacks image thumbnail
I have recently transferred my blog https://founder360mag.com/ to hosting on digital ocean. When trying to share an article on Facebook, the post does not display the article’s thumbnail. I tried to debug it and I got this message “Could Not Connect To Server Check that the webserver is running, and that there are no firewalls blocking Facebook’s crawlers”
Upon searching this error on Google, there were some suggestions that it could be a hosting issue where the host has blocked Facebook access to my site.
Could this be true? If not, kindly assist with whatever solution.
