Posting in FB - 404 requested page not found [SOLVED]

Hello!
When I post in the Facebook FC main page, I'm getting error - 404 requested page not found.

This only happens with FlexiConten. Other components behave correctly.So, when we post the main page of site  directory.audio  the link goes like this -  directory.audio/?fbclid=IwAR1w9zh5Bn9Gxr...cbf5U356h6orhN48ul8s Maybe that's the reason.

its realy strange i can reproduce it for your link
but
i check opengrap ckecker, no error smallseotools.com/open-graph/
developers.facebook.com/tools/debug/?q=h...ectory.audio%2Ffr%2F says that you need to add image in opengraph
...

I've added image.
No any errors for URL directory.audio/fr/
Try to check domain name directory.audio in developers.facebook.com/tools/debug/
It displays the same error.
developers.facebook.com/tools/debug/?q=h...2F%2Fdirectory.audio

P.S. I see in the code of main page this - <meta property="og:url" content=" directory.audio/https://directory.audio"/ >
Is it FC creates this tag?

P.S. Ok, I see. it's JFB Connect component problem.
But not only.
FC generates different URls for the main page.
So, how to remove / from the end of canonical URL for the main page?

Any ideas?

hello as i say i think you have a problem on your site site only
if you check demo site flexidemo.com3elles.com/realestate/demoj4/ and share it on FB no error
what is your joomla and flexicontent version ?
did you have a redirection or a SEO Tools ?
