I'm trying to validate my Hostinger DNS on AWS Certificate Manager.
I tried using e-mail validation method
And it still failed
Also, using validation by adding CNAME and value in my DNS Record like this
And confirming using nslookup
And instantly gave failed
I searched for some solutions like this one and nothing helped

See the docs: https://docs.aws.amazon.com/acm/latest/userguide/setup-caa.html
