Nexus Packer script is not able create an AMI

[somnathg-fullstack]

When I executing the packer script after installing the nexus it is waiting to get the response from localhost for eternity. Packer build needs to forcefully terminate and no AMI is getting created

until $(curl --output /dev/null --silent --head --fail http://localhost:8081); do
printf '.'
sleep 2
done
