First Time creating a WordPress Website & I’m Having Problems.

I’m new to creating a website and am currently trying to get a website up using [WP.com]) and trying to connect a domain to the WordPress site I started. I got it Connected, and everything seemed to be perfectly fine; when I tried to turn the website to the public, I got a bunch of error pop-ups. Some of them are

1. “Jetpack is unable to connect to your domain because your domain’s DNS records aren’t pointing to your site. ”

Did I do something wrong in my DNS records? I believe I followed the WordPress instructions down to the Letter. Any information would be helpful!

Thank you guys
