jetpack connect error on mysite

Hi,

In my website wordpress admin page connect to jetpack, it is showing some error. How to solve that….

I am new to wordpress. my web url: http://stlourdespunnainagar.org/wp/

Error:
Your Jetpack has a glitch. Something went wrong that’s never supposed to happen. Guess you’re just lucky: xml_rpc-32700
Try connecting again.
Error Details: The Jetpack server could not communicate with your site’s XML-RPC URL. Please check to make sure http://stlourdespunnainagar.org/wp/xmlrpc.php is working properly. It should show ‘XML‑RPC server accepts POST requests only.’ on a line by itself when viewed in a browser and should not have any blank links or extra output anywhere.

Regards,
Bright Jani
