Hello, it is good that you have this domain, but have you done something like SEO techniques, ti make it more popular. did you get links from somewhere. Are you sure that Google even knows about it ? There is no reason that Google blocks .co websites. So check if Google knows about this by typing:
site:mysite.co with http in front of it.
If you get your site as a result, then Google has indexed the page, if not, you should put some effort to let Google know about it.
Regards
