Cant assign my arsys domain to a AWS EC2 instance

I want to assign an external domain (arsys.com) to my EC2 instance

I bought a .eu domain from the arsys domain provider: "mydomain.eu".

I have an EC2 instance on AWS, with an elastic ip and public domain.

Public DNS: ec2-1-2-3-4.eu-west-1.compute.amazonaws.com
Public IPV4: 1.2.3.4

I have configured my domain for this machine in arsys.com this way:

Control panel -> Domains -> DNS Servers ->

Name DNS Server: ec2-1-2-3-4.eu-west-1.compute.amazonaws.com IP: 1.2.3.4

Control panel -> Website -> DNS ->

DNS Entry: mydomain.eu Type: A Value: 1.2.3.4
DNS Entry: www.mydomain.eu Type: CNAME Value: mydomain.eu
DNS Entry: control.mydomain.eu Type: CNAME Value: pdc.servidoresdns.net

when I access "mydomain.eu" through the browser, I get the error that this website cannot be accessed

I have configured the instance security group so that it allows anyone to access it through the HTTP protocol (port 80) and HTTPS (port 443).

I have also set up the ICMP protocol to be able to ping both DNS and IP.

What could be wrong?

Solution

I think the issue is on this part

Control panel -> Domains -> DNS Servers ->

Name DNS Server: ec2-1-2-3-4.eu-west-1.compute.amazonaws.com IP: 1.2.3.4

The thing called Public DNS: ec2-1-2-3-4.eu-west-1.compute.amazonaws.com of EC2 is not meant to be the address of a DNS server

What you just did is that: You specify to arsys that : Please let ec2-1-2-3-4.eu-west-1.compute.amazonaws.com manage DNS for my domain which is not possible

Please remove that line and let arsys manage your DNS. Or better, use CloudFlare / CloudFront to manage your DNS
