Hi @petr008,
Thanks for reaching out!
I checked the URL you shared using the Facebook Debugger Tool and found a strange thing.
It appears your URL is being redirected (301) to this URL (https://www.facebook.com/externalhit_uatext.php/) only when Facebook crawlers are trying to crawl.
Here’s the test result:

Here’s a screenshot of the redirection – https://a.supportally.com/i/Cfhe8n
This is creating several 301 redirects to your site’s URL. The problem affects your entire website, as shown here: https://a.supportally.com/i/d5BTq7
Though it’s tough to say anything without directly investigating the problem, I can assume that there is some form of .htaccess redirection set particularly for the Facebook user-agent, which is triggering the redirection for Facebook only.
Here you can see Google can crawl your site fine – https://search.google.com/test/rich-results/result?id=8ZnKXdK1YySh7aYsXI2rdw
Here’s an example of how the .htaccess redirection rule should look like (not exactly like below but similar):
RewriteCond %{HTTP_USER_AGENT} facebookexternalhit/[0-9]
If you are unable to figure out the root cause of the redirection, you may also get in touch with your hosting provider, and I believe they’ll be able to assist you with this one.
Let me know how it goes. Looking forward to helping you.
Hello,
so the cause is already known.
I initially went through social settings, then security plugins, redirect settings and still nothing.
Now I got this response from my hosting provider:
Hello,
Unfortunately, the facebokexternalhit robot is overloading our servers at once, and Facebook is on the hook, so we block this robot by default.
I have unblocked your domain. If robot access to other websites is necessary, please send us a list of them.
So I apologize for looking for an error in your plugin settings.
