For some reason card validator doesn’t seem to be able to retrieve metatags from my website, even though it’s fully scrappable through Twitterbot & cURL.
All I get is:
INFO: Page fetched successfully
WARN: No metatags found
Here’s an example url I’m trying to implement cards on: https://www.dziwne.com.pl/jedzcie-wiecej-psow-zaleca-swoim-glodujacym-rodakom-kim-dzong-un.html
I’ve tried everything, compared headers to some other working websites and even matched the HTML structure, but to no effect, validator can’t read metadata from my website.
What could be the reason for this? Any tips on what might I be doing wrong?
Update: I’ve made a small test website and put in on the same server and… well, metatags work perfectly on it, which confuses me even more. It’s 100% not a server issue and I don’t see any errors in the markup of my “big” website.
Update 2: Server’s firewall doesn’t block Twitter’s IPs, I’ve even copied the files from one domain to another and… well, everything works just fine on the other domain, even though both are hosted on the same server.
Update 3: Was wondering if it might have something to do with CloudFlare, but after turning it off nothing has changed, so I guess not :(.
