From my point of view, everything looks right. You would have to ask in their support forum why Jetpack is reporting this: https://wordpress.org/support/plugin/jetpack/
Hi there! In checking your site through a third-party tool we do see that you have your domain pointed to WordPress.com. If that is correct then you would want to check with that provider to confirm that the IP that you have set for your A record is correct. If it needs to be updated our live support team would be able to assist with updating the A record with the IP that that was provided by that service.
If the website resides on a Bluehost server, but is pointed to another provider such as WordPress.com, it could result in the URL not matching error. If the website is on Bluehost, updating the A record or nameservers to Bluehost could correct the issue. It is hard to say with out more information. Our live support team would be happy to help with any issues on the Bluehost end of things once your domain is pointed back to us.
