I’m debugging twitter cards tags on site on my local home IP. After a few tries validator begins to say:
*.%IP% is not whitelisted for website card
And after this: no preview, nothing. Validator becomes useless. The only thing I can do is to request approval (which requires the site description). I don’t need to approve my home IP as it is used only in debug purposes and obviuosly will never appear in real tweets. Moreover: I can’t provide the site description as there is no site here. Only debug webserver with a few pages.
At the beginning of my debug, validator works OK (and said that IP is OK).
The only my question is WTF? How should I use validator if it bans IP after few tries?
