I cannot preview the card on my website. All the information is configured. Site one of the link is https://www.theblockbeats.com/news/21463 all problems are eliminated. You can only ask questions here

#2

I’m seeing a summary card when I validate that link, perhaps a temporary network issue?

#3

I tested it. Just the URL link I asked was available, other site connections are still invalid

#4

I’ve just validated several of the /news/ URLs and they show a summary card in the validator. The home page has no card data, and the 404 / error page redirects also have no card data. What other site connections are you seeing where the fetcher reports unable to resolve the address?

Thank you for your reply. Such as https://www.theblockbeats.com/news/21492, or https://www.theblockbeats.com/news/21490, and so on. Is the domain name https://www.theblockbeats.com/ site under all/news/url cannot show preview CARDS. “ERROR: Fetching the page failed because the fetcher cannot resolve the address.”

This is what I verified with the validator

I do see “request timed out” errors on a few links but not address resolution errors, which is why I’m wondering if this could be a network issue. Generally the fetcher expects sites to respond in just a few seconds (less than about 10 seconds), for performance, otherwise it will move on.

Strange - unable to reproduce this:

Thank you for your reply. Oddly enough, I didn’t get any information, the same link. Is it related to countries and regions?

I’m not aware of that being a limitation.

#11

Another weird thing is that when I post a link on Twitter, some of the URLs are successful, and some of the URLs don’t respond at all

The preview does not always show up in the initial Tweet editor - I just had the same experience with my test account, but when I went back to check afterwards, the card shows just fine.

#13

Thank you for your reply. Then what should we do in this situation? Because we really need these cards.
