I am getting the erro:
INFO: Page fetched successfully
WARN: No metatags found
My test page is http://www.palmeiras.com.br/twitter-summary-card-test.php
The metatags are all included but it is still not validating. Could be something related to CloudFlare’s CDN service?

I FOUND THE ERROR!
Solution:
** Posting here as the topic is already closed (today is may/29/2017). The error is that the site is using CloudFlare’s CDN. The default site configuration is locale PT-BR (Brazil). So for all international accesses (including USA), CloudFlare requests a reCaptcha authentication before redirecting to the site’s default page. The server sends a 403 Forbidden status message to the browser.
