Cannot enable ssl on subdomain

I’m trying to resolve ssl issue.
I have a subdomain: app.olympusfinance.io hosted here in netlify with an ip address: 75.2.60.5
My main domain is hosted in hostinger: 31.220.110.192

I had ssl certificate in hostinger before I transferred my subdomain here.
Now I’m getting this error message: We could not provision a Let’s Encrypt certificate for your custom domain.
I already uninstalled my ssl from hostinger thinking it’s a conflict, but still getting the same result. Please give me some clue or pointers on how to solve this.

Hi, @OlympusFinance. The SSL cannot be provisioned because this AAAA record doesn’t point to Netlify:

app.olympusfinance.io.	14400	IN	AAAA	2a02:4780:3:697:0:6aa:e3b1:1

If you delete that DNS record above the ssl provisioning should be successful.

By the way, our external DNS instructions recommend making a CNAME record and not an A record for all subdomains:

The recommended record would look like this (replacing <SITE SUBDOMAIN> with the actual site subdomain at Netlify):

app.olympusfinance.io.		1800	IN	CNAME	<SITE SUBDOMAIN>.netlify.app.

If that does not resolve the issue or if there are other questions, please let us know.
