The following link is helpful in answering how to unblock port 25: [Remove port 25 restriction from your EC2 instance | AWS re:Post](https://repost.aws/knowledge-center/ec2-port-25-throttle). However, my question pertains as to why it's blocked. Doing some research I've found a list of reasons as to why port 25 might be blocked or throttled by hosts and ISPs, but I was hoping for a more official explanation from AWS as to why it's blocked here. Thank you.
Hello, Is it possible to assign a domain name to ec2 instance. My goal is to have ec2 instances with my custom domain assigned for example: app-1.example.com For now my idea is to programmatically assign or remove domain name based on instance state. Maybe there is a AWS service that could help me?

Hello everyone, as a complete beginner in AWS, I'm following a coursera course for AWS beginners. One of the first exercises is to create a EC2 instance via the AWS console. They provide us with a little script that boots up on an app on the virtual machine, and should then be accessible with an HTTP call on the public IP. I don't what's exactly going on but it seems that the page is loading forever and then times out when I try to access it on a web browser at the address http://<public-ip-address> Does anyone know what could be going on ? Here are the details of the EC2 instance I've launched : Amazon Linux AMI t2.micro HTTP protocol (source: everywhere) I've configured a key pair default VPC chose first subnet ![subnet](/media/postImages/original/IMf2NUIq3bRGaWDyihOOMz1A) ![subnetmapping](/media/postImages/original/IMSEVBK6LdS3WwRIvIJeT2yw) I also have an error when trying to use EC2 Instance Connect. (maybe because I have only configured HTTP and not SSH) ``` Failed to connect to your instance EC2 Instance Connect is unable to connect to your instance. Ensure your instance network settings are configured correctly for EC2 Instance Connect. For more information, see Set up EC2 Instance Connect at https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-instance-connect-set-up.html. ``` If anyone could help me debug this, that would be really helpful. Thank you for reading me !

I am trying to get a handle on how to you define an ALB, its Listeners, Target group and Security groups in a CF Template. So I wrote out this sudo code listing.
