I am trying to setup a subdomain in Route53 to point to a load balancer in AWS. (I'm using a load balancer as it seems to be required in order to use the ACM-provided SSL certs)
This is what I've achieve/attempted so far:
Everything was created in the same AWS account including registration of the domain name.
√ - The load balancer is setup properly; in that I can load my landing page in the browser (from the EC2 instance) providing the long DNS name url of the load balancer.
√ - I can setup any number of subdomains in Route53 for this domain instantly and without problem for an s3 bucket or EC2 instance.
Therefor there doesn't seem to be a problem specifically with either my domain or the load balancer on their own.
The setup for my record set it as follows is as follows (following a couple of the AWS docs)
name: subdomain [.mydomain.com] Alias: Yes Alias target:
( no code to share )
Expected: The same outcome of typing in the full load balancer dns name in the address bar.
Actual: Browser message
This site can’t be reached
subdomain.mydomain.com’s DNS address could not be found. Diagnosing the problem.
DNS_PROBE_STARTED
and then
subdomain.mydomain.com’s server IP address could not be found.
DNS_PROBE_FINISHED_NXDOMAIN
☺ Thanks ☺
