Cannot connect to web server with public IP address.

Question

I have an EC2 instance that I've installed Apache (HTTPD) on. I can get the server running on the instance, yet when I try to access the public IP address from the console, I get the "Took to long to respond" page.

For testing purposes, I made my instance apart of a security group where the inbound rules allow all traffic from any source, yet I still can't connect to the server.

Just to be sure, have you checked by typing from "http://" into your browser?

Sometimes, as is the case when using the open address of the Management Console, you are unintentionally accessing the site via https.

Hello.

Is Apache running on EC2?  
If you are using Amazon Linux 2023, you can check whether Apache is running with the following command.  
```
sudo systemctl status httpd
```
If it is not started, run the following command to start it.  
Also, by running the "enable" command, you can configure Apache to start automatically even if you restart EC2.  
```
sudo systemctl start httpd
sudo systemctl enable httpd
```
By the way, are you accessing the public IP address of EC2?  
Have you ever accidentally accessed a private IP address?  
Can you confirm that you are accessing it using the following in your browser?  
```
http://ec2-public-ip
```
