Failed to crawl url on every page of my website


when I try to validate my Twitter Cards I always have this error message :
"Failed to crawl url, debugId: 4075040589539-383174"
Eg of page :

Here the metas

<meta property="twitter:card" content="summary">
<meta property="twitter:site" content="@Metalorgie">
<meta property="twitter:title" content="Once More Round The Sun">
<meta property="twitter:description" content="Once More Round The Sun(2014) de Mastodon">
<meta property="twitter:image:src" content="">

(I copy / paste the value into the Twitter Card Validator / Try Card and it display a card)

Any idea on the problem with my code?



I tried this :

curl -v -A Twitterbot

And got the content of my page.


where U write this Metalorgie ???


Sorry, our system was down a bit. I now see it working; can you try again and hit the “Request Approval” button?


Indeed it’s OK now, thanks!


In a terminal (linux / macos have one, windows too but don’t know exactly how to use it with curl)
