I'm having trouble accessing RDWeb Access Server via internet browser using my FQDN (https://ifodgw.abacushub.io/rdweb) externally. I am able to access it externally using the elastic ip address 52.16.145.145, and internally using the FQDN. Pinging externally, from my local machine:

Ping request could not find host idodgw.abacushub.io. Please check the name and try again.
My remote desktop services setup is on an AWS EC2 instance, using Windows Server 2012.
Instance ID: i-1ce67396
Instance Type: m3.large
Availability Zone: eu-west-1a
Instance state: running
Status Checks: 2/2 checks passed
Alarm status: None
Public DNS: ec2-52-16-145-145.eu-west-1.compute.amazonaws.com
Public IP: 52.16.145.145
I've created an A Name record with the FQDN and IP address on Linode's DNS Manager for the server in my domain zone. I also have a different A Name record hosted in the same domain zone for a similar setup on different AWS servers, in a different active directory with the same domain name, and this resolves correctly: https://gateway.abacushub.io/rdweb,
A/AAAA Records
Hostname IP Address TTL
gateway 54.77.226.3 Default
ifodgw 52.16.145.145 300 (5 minutes)
As a workaround, I'm able to add this line to my local hosts file:
52.16.145.145 ifodgw.abacushub.io
This isn't an ideal fix though, as I'd need to do this for every client machine.
Any insight as to what I'm doing wrong would be appreciated! Thanks.
