Card whitelisted but no image shows


Hello Im Wanny

Our site is a korean potal news service.

and url has validated and I see the green text like below

“* is whitelisted for summary_large_image card”
“INFO: Page fetched successfully
INFO: 15 metatags were found
INFO: twitter:card = summary_large_image tag found
INFO: Card loaded successfully”

and our test page is

also I added “allow for twitterbot” in robots.txt
but Pic does not show up.

we use og tag for the images

<meta property="og:image" content="">

could you help us please?
I have no idea what’s wrong

PS : could you let me know when the TwitterBot does crawling the images exactly?

No image shows only pc not mobile

I found this reason that we didn’t work on robots.txt of ours global CDN server, only domestic.

now it works fine. thanks. =)
