Hello,
Thank you for contacting the support, and sorry for any inconvenience that might have been caused due to that.
Can you please upload at least 600x315px image? Recommended size is 1200x630px. Clear the cache after doing so and see if the image started to show when you share your link.
You may test your URL here:

Also, can you please check your domain name servers if they are inputted correctly? Facebook sometimes is not able to fetch the data cause of wrong server name. If that’s the case, you need to get in touch with your hosting provider and ask for the right names.
Let me know how it goes.
Looking forward to helping you.
