If your site is configured with A records, you’ll need to change the IPs it’s pointing to before you’ll be able to get a cert:

185.199.108.153 185.199.109.153 185.199.110.153 185.199.111.153

EDIT: You’ll also need to remove and re-add the domain in the repository settings after doing that too to trigger it to request a cert.

Can you expand on how to perform the steps added in your edit? Thanks!

Go to the GitHub pages section of the repo settings, delete your domain name from the custom domain input, hit save, then add it back and save again.

If it’s still not working after that the you can contact support and they can press a button on the back end to trigger a cert request.

Didn't work for me. Might have something to do with the fact that I also have a CNAME file in my repo. I'll reach out to support

Could you please update us once it's done? I have got exactly the same issue.
