it's likely an issue with network configuration or restrictions within your AWS environment. Here are some steps you can take to troubleshoot and resolve the issue:

Ensure that the security group associated with your AWS instances allows outbound traffic to port 443 (HTTPS), which is commonly used for accessing websites securely. If the website is served over HTTPS, make sure that outbound traffic to port 443 is allowed.

Verify that the network ACLs (Access Control Lists) associated with your subnet allow outbound traffic to the website's IP address or domain name. Network ACLs act as a firewall at the subnet level and can block traffic if not configured correctly.

If your AWS instances are in a private subnet, ensure that there is an internet gateway attached to the VPC (Virtual Private Cloud) and that the route table associated with the subnet routes traffic to the internet gateway for internet-bound traffic.

Check if DNS resolution is working correctly on your AWS instances. Try resolving the domain name of the website (www.tmdn.org) using tools like nslookup or dig from your AWS instances to see if they can resolve the IP address of the website.

If your AWS instances are behind a proxy server, ensure that the proxy configuration is correctly set up to allow access to the website. Check the proxy settings in your instance's network configuration or application settings.

Some organizations use DNS filtering services or DNS-based security solutions that may block access to certain websites. Verify if there are any DNS filtering rules in place that could be blocking access to the website.

Hope it clarifies and if does I would appreciate answer to be accepted so that community can benefit for clarity, thanks ;)
