“Unable to render card preview”


Any website in my hostelling can be verificated…
All of them test results is: “Unable to render card preview”


My tobots.txt:
User-agent: *
Disallow: /wp-admin/
Allow: /wp-admin/admin-ajax.php
User-agent: Twitterbot

Is this a problem with my DNS o server?
Help me please?


Which of the troubleshooting steps have you tried?

I just ran the third test:

$ curl -I -A Twitterbot http://www.lawyersportslaw.com/

HTTP/1.1 403 Forbidden
Server: nginx
Date: Mon, 17 Jul 2017 09:29:30 GMT

So, your server is blocking the Twitterbot user-agent from accessing the page.


Hi Andy! Thanks for reply!
I dont know why the Twitterbot cant access…
meta, robots.txt and htaccess OK
"may be blocking web crawler access to your site. You should contact your hosting provider and ask them to ensure they are not blocking Twitter access by either IP or ASNUM. Twitter’s aggregate outbound IP ranges are and Twitter’s ASNUM is AS13414… "???
I just contacted to my hosting provider …


Thank you so much for your help!!!
My hosting provider resolved the problem !
