Whitelist request was rejected



I am facing problem while validating the Twitter Card. I am getting error message as whitelist request was rejected 21 days ago.

I want to know what is the meaning of this. Also i got warn message as

INFO: Page fetched successfully
INFO: 19 metatags were found
INFO: twitter:card = player tag found
WARN: Not whitelisted

Can anyone help us in resolving this issue?

I don’t understand what is the meaning of “Not whitelisted”. I assume the URL i am used is not whitelisted one. if so How do i get my URL Whitelisted.
