FB Developer Tool showing 403 Forbidden about sharing link website from Facebook
1

My website: https://congdoanhoabinh.org.vn

Is working fine with Twitter and Zalo but not working with Facebook. I have added og:title and description and og:image but showing 403 Forbidden. Reason from Facebook is due to robots.txt but I don't know how to solve. Give me detail for this error. Thanks!
