SSL certificate stuck – “certificate parameter is required when updating an existing certificate”

Hi Netlify Support,

I need help with an SSL certificate that I cannot provision for my custom domain.

Netlify site: sparkling-pie-f8e78c.netlify.app
Custom domain: great-a-tude.co.za

My DNS configuration has been verified successfully by Netlify.

My DNS records are:

When I click Provision certificate under HTTPS, I receive this error:

“certificate parameter is required when updating an existing certificate”

I have already clicked Verify DNS configuration, and Netlify confirms:

“DNS verification was successful ✓”

I also tried provisioning the Let’s Encrypt certificate again, but the same error occurs.

Could you please check whether there is a stale or existing SSL certificate associated with my site and reset/clear the certificate state so that a new Let’s Encrypt certificate can be provisioned?

Thank you.
