I am creating an A record for sub domains on my parent domain's hosted zone. The record gets created successfully but when I visit the subdomain it does not resolve to the sub domains ec2 server all the time. It will work for a few tries then not work for a few minutes. When i visit the public IP it always work, it's just when I want to visit the subdomain name. Do I need to add anything else so that is resolves properly?
My A record info:
Name: dev.alio.com
Type: A
Value: 52.24.143.16
TTL: 300
dig dev.alio.com
output?
