bncert says my domain resolves to a different IP address, but it is not

I have this probably easy problem:

I'm trying to use bncert-tool on my aws wordpress website machine. I transferred my domain from elsewhere to aws, made an hosted zone, also the static ip address.

nslookup works, writing the right ip.

Reading this answer i went to and every query gets an almost all green lights.

Trying to simply reach the website with a browser works: i can see my website normally (except that tls warning).

Can you help me with this? Thank you all.
