Large Image Twitter Card works for individual posts but not primary page

Is anyone else having this problem? I’ve got my Large Image Card working for my blogger website, but it’s only working now for individual posts and not when I tweet the domain name’s URL. It’s saying my URL isn’t whitelisted, which shouldn’t be necessary for a Large Image Card right?

For instance when I validate http://www.theblotsays.com/2015/08/teen-wolf-tw-resin-figure-by.html I get:

INFO: Page fetched successfully
INFO: 12 metatags were found
INFO: twitter:card = summary_large_image tag found
INFO: Card loaded successfully

But when I validate http://www.theblotsays.com I get:
INFO: Page fetched successfully
INFO: 5 metatags were found
WARN: Not whitelisted

Thanks for the help!
