Why does Facebook sharer see my old website

I have a domain name and it had a wordpress cms in it, I re-created the website using another cms (not wordpress). When I try to share the articles or any page, it gives me in the FB sharer badge "page not found", but when clicking on the link .. it opens the page normally as expected.

I tried using Facebook Debug and it still gives me "Bad Response"enter image description here

When clicking on the button "See exactly what our scraper sees for your URL" in the debugger, it shows me the source of the wordpress page, although I changed the name servers and it is pointing to the correct host.

Any ideas?

Solution

  • and it is pointing to the correct host

    For both IPv4 and IPv6?

    Facebook gives preference to the latter, so make sure that the records for both point at the new server now, resp. check that you got no old records for IPv6 still pointing to the old server somewhere, should the new one not support IPv6.
