Hello,
We’ve checked your site and found that Rank Math is successfully generating your og:image

Our plugin has nothing to do with the SSL certificates. So, in order to resolve this issue, we suggest you to get in touch with your hosting provider and inform them about the error.
Hope that helps and please don’t hesitate to let us know if you have any other questions.
