Custom Domain SSL error

I can’t get a Let’s Encrypt certificate for my custom domain. Any idea how I can fix this? The DNS records of my domain are already pointing to Netlify.

The error I get is: We could not provision a Let’s Encrypt certificate for your custom domain.
My netlify site is: webspek.netlify.app
My custom domain is: daronobrien.xyz

And I have a issue with the mail. I can only send mails and don’t receive anything. I pointed the mx records already. How can I fix this?

Thanks in advance

I’ve routed this ticket to our helpdesk, we’ll follow up via email.
