Certificate for custom domain is not being issued

I want to create a certificate for a subdomain: test.kini-app.co.za

I have created my A, AAAA and TXT record.
They are being recognised.

But the certificate doesn’t go beyond ‘Issuing’.

This has been like this for a couple of hours already.

I have removed my AAAA record for testing purposes.

It is working now.

It started working after removing AAAA and after adding the ACNE challenge.
