Unable to obtain SSL/TLS certificate for my co.uk domain

hi, i have purchased a co.uk domain and when i try to connect it with netlify using external DNS, im unable to get the SSL/TLS certificate. I have set the configuration correct but still im unable to obtain it.

The purchased domain is buteconstruction.co.uk.

Im currently running the site with buteconstruction.netlify.app.

I would like to know what i need to do in order to obtain the certificate for my purchased co.uk domain.
Please assist me to resolve this issue

You’ll also want to delete the DNS zone for buteconstruction.co.uk.
