Images not showing up on cards



Hi -
I read a lot of topics about this issue but none of the solutions I found applied to my case.

The image I’m trying to load is from our CDN:

TwitterBot is not blocked, in fact, if I change my UA to “TwitterBot/1.0” I am able to retrieve the image.

This is the temporary test page I am running through the validator to debug this:
And the meta tag in the HTML is:

<meta name="twitter:image" content="" />

(Note that the ?w=1400 is added by WP but it doesn’t make any difference)
When I run through the card validator no errors are thrown and the meta tag twitter:image is actually fetched, but the image won’t display.

Am I missing something here?


Nevermind - there’s a robots.txt file that is actually blocking the bot.
Still don’t know why my manual override of the UA works though
