I have a basic Django website hosted on EC2. It is accessabile over the internet when I use the ipaddress. But I want to use my newly purchased domain example.net (purchased from Namecheap). I configured Rout53 for DNS services. When I try to access my website using example.net it doesn’t do anything and gives below error on browser:

"This site can’t be reached example.net refused to connect.
Try:

Checking the connection
Checking the proxy and the firewall
ERR_CONNECTION_REFUSED"

When I checked the logs on my EC2 server, it does not show any log if I hit example.net on browser but it shows logs when I hit “ip address”.

I performed all below checks and all is working fine as expected:

1. DNS Records: Verify DNS records in Route 53. – I checked both A and CNAME record and it is correct
2. Security Groups: Confirm security group rules allow HTTP and HTTPS traffic. – Both HTTP and HTTPS inbound rules are open for all.
3. Verify ALLOWED_HOSTS in Django – This is how my ALLOWED_HOSTS looks like in my Django settings.py [‘my EC2 elastic ip’, ‘example.net’]
4. Firewall Settings: Confirm ufw is inactive or appropriately configured. – I don’t have any firewall configured
5. Domain Resolution: Verify using dig or nslookup. – I tried this command on my EC2 instance “dig example.net @” and I get all details as below

6. Browser Cache: Clear cache or use incognito mode.

7. Server Reachability: Test local server response using curl. – Curl with my EC2 ip is working fine but curl with my domain name is not working.

8. DNS Propogation: like Whatsmydns.net to see if the DNS records have propagated globally. – This shows green ticks globally.

Please help me or suggest to me what I am doing wrong and where.
