Newbie: Error 404 pixie proxy

Hello! Total newbie! Using cloudflare pages to host musicbylianne.com. It views properly in development. Domain registered at porkbun. I contacted porkbun and they said the error 404 (002) pixie proxy means that the DNS has not been set up correctly on cloudflare side….but I have no idea how to check it or fix it. It’s a simple static html site. I’m not sure even what info to provide to troubleshoot. Here are some pictures of the DNS setup on pages side. Please help! Thank you!
