Hello,
Thank you for contacting Rank Math, and sorry for any inconvenience caused.
I checked the URL with Facebook Sharing Debugger, there is a Curl Error.
The issue you are facing is pretty common with W3 Total Cache users. The Gzip compression option is causing this issue, disable this option from W3 Total Cache Performance > Browser Cache.
After that, clear the cache.
This should fix the issue.
Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
