[Plugin: jetpack] site_inaccessable

Hey,

I keep on getting an error when trying to activate jetpack “IXR -32300: transport error: http_request_failed Couldn’t resolve host ‘samsherar.co.uk'”. I have no plugins activated and I have modified .htaccess to allow for xmlrpc.php (http://samsherar.co.uk/blog/xmlrpc.php?rsd) and the curl callback comes back with this:

{"error":"home_missing","error_description":"The required "home" parameter is

What can I do?
