404 error, when posting page link on Facebook

Hello

Having problem with SEO Open graph. When I want to publish a post on facebook with my domain link it get’s a 404 Error image instead of Opengraph Image.
Any Idea why? But that error is only when I post my domain name. Any pages within website works fine.
Confused :confused:
