Hi @hazycora, welcome to the GitHub Support Community!

I’ve taken a look at your site and it looks like a certificate has been successfully issued for this domain: https://www.hazycora.com/.

Be aware that GitHub doesn’t currently support certificates for both the apex domain and the www domain, only the exact domain you put in the custom domain input, so visiting https://hazycora.com/ will still result in a certificate error even when http://hazycora.com/ successfully redirects.
