Facebook does not like FTH?

I'm sure this has bee logged before, but I'm not clear as to what to do.
CLUB: 1879279 - Donna Young
Can't get facebook to accept my FTH url: developers.facebook.com/tools/debug/?q=h...stersclubs.org%2F%20

Getting 4 msgs:
1. Could Not Connect To Server. Check that the webserver is running, and that there are no firewalls blocking Facebook's crawlers.
2. Curl Error: Curl error: 56 (RECV_ERROR)
3. Inferred Property: The 'og:image' property should be explicitly provided, even if a value can be inferred from other tags.
4. Missing Properties: The following required properties are missing: og:url, og:type, og:title, og:image, og:description, fb:app_id

I'm not a developer, so I'm afraid, I don't understand this
If you could point me in the right direction, I would appreciate it.

Thank you,
Donna Young

You would need to tell us what IP facebook is using to scrape the site.

I'm not sure how to figure that out.

I entered this address in the 'scan': 1879279.toastmastersclubs.org/

and I also tried it with : lsot.toastmastersclubs.org/

Can you derive the IP from that?
Donna

I did see this, but am not sure how to interpret it:

developers.facebook.com/docs/sharing/webmasters/crawler
