Public IPv4 works, domain name doesn't

Domain testify4love.com is registered at godaddy.
Created EC2 instance on AWS.
Created a hosted zone testify4love.com on AWS.
The public IPv4 address works in the browser: http://54.203.231.30/
Entered the four NS values from AWS as DNS custom nameservers in godaddy more than 48 hours ago.
Testing http://testify4love.com/ in the browser, I get:
This site can’t be reached testify4love.com’s server IP address could not be found.
ERR_NAME_NOT_RESOLVED

On https://dnschecker.org, the A and CNAME records show as not propagated, but the NS and SOA records show as propagated (with the expected four NS values).

Edit:
Now the error is DNS_PROBE_FINISHED_NXDOMAIN
