Issue: Twitter cards are not working on specific domain. Any urls shared on Twitter from my website don’t have a card. Demo live tweet: https://twitter.com/martijnoud/status/872530520722243586
When running the card validator it simply says
Unable to render Card preview and the log says
ERROR: Failed to fetch page due to: HttpConnectionTimeout.
Troubleshooting steps tried already: Yes.
- The website loads normally and fast
- Twitterbot and images are not being blocked by robots.txt (or similar)
- Curl shows the rich snippet in the source
- The card snippet is valid (generated by Yoast SEO plugin v4.9)
- Probably not related to SSL handshake issues (Test from ssllabs.com)
