I cannot connect to my EC2 Instance via HTTPS Protocol (I click "open address" button in Instance Summary next to Public IPv4 Address")

Question

Good Day,

Please help me.

In AWS Skills Builder, Module 2 - Lesson 16 - Demonstration: Launching the Employee Directory Application on Amazon EC2 it guided me to create EC2 instance.

I create instance per tutorial video and I click open address(see attached ss) and error page(see attached ss)...

I can't connect to my instance via EC2 Instance Connect. I go to Systems Manager and start session, I run:
sudo -i
sudo yum install httpd -y

I think maybe now I can connect EC2 Instance Connect? Yes, nice. 
I verify that I can connect, but I still keep running commands in Systems Manager Session. Now, I run:
sudo systemctl start httpd
sudo systemctl enable httpd

I know I can now click open address (see attached ss) in instance summary tab for my instance, and it will take me to error page(see attached ss). After this, I can try http by removing the s from https in url, and successful!

However, could you please help me in explaining why is it that the script is not working properly? I know I created Amazon Linux 2023 Instance, so I used the Amazon Linux 2023 Instance user data script from the tutorial video (please see below).

Amazon Linux 2023 user data script:

#!/bin/bash -ex
wget https://aws-tc-largeobjects.s3-us-west-2.amazonaws.com/DEV-AWS-MO-GCNv2/FlaskApp.zip  
unzip FlaskApp.zip
cd FlaskApp/
yum -y install python3-pip
pip install -r requirements.txt
yum -y install stress
export PHOTOS_BUCKET=${SUB_PHOTOS_BUCKET}
export AWS_DEFAULT_REGION=
export DYNAMO_MODE=on
FLASK_APP=application.py /usr/local/bin/flask run --host=0.0.0.0 --port=80

"in Insert-Region Here I put the region of where I am us-east-2"

Finally, could you please help me understand why the final result of "how it looks for me"(see attached ss) is not the same as "how it looks for instructor"(see attached ss). Also, help me understand why I can't just click open address and connect to my instance like I see in the tutorial video?

P.S: 
1. All system checks are passed and instance is in running state

2. Internet connection is stable and I am able to visit other website (for example, Gmail)

3. Security Group has correct Inbound/Outbound rules for SSH, HTTPS, HTTP (In AWS Skills Builder, Module 2 - Lesson 16 - Demonstration: Launching the Employee Directory Application, the lesson guided me to set up HTTPS/HTTP inbound rules) are correct.

4. Subnet is correct, and the Access Control List is correct, and the Route Table has a correct Internet Gateway that is active and good.

5. Request timed out when I ping my website.

6. I can access my website via HTTP, just not HTTPS, and again there is the fact that it just says [It Works] vs [Employee-Directory-App] like it shows in the video.

I posted 3 pictures in postimg.cc because I could not attach screenshots.

Please help me, Amazon Support couldn't help me, and I'm too broke to afford paid technical support, but  I can't give up on learning aws, this is the first time in my life where I actually feel like my life has a meaning. I need to learn this like I need to breathe.

Accepted Answer

This skills tests DOES NOT setup HTTPS. As per the instructions this will only work over HTTP.
https://aws-tc-largeobjects.s3-us-west-2.amazonaws.com/DEV-AWS-MO-GCNv2/exercise-3-compute.html

As part of the instructions in task 2, step 3 it states:-

**In a new browser window, paste the IP address that you copied. Make sure to remove the ‘S’ after HTTP so you are using only HTTP instead.**

There are no steps to setup HTTPs in this excercise. You have completed the task correctly. 
There is nothing to worry about, all is good.

Answer

Hello.  
You have httpd installed, but installation is not required.  
If httpd is installed, stop it with the following command.  
```
sudo systemctl stop httpd
```
I also ran the user data script and was able to get it to work correctly.  
```
#!/bin/bash -ex
wget https://aws-tc-largeobjects.s3-us-west-2.amazonaws.com/DEV-AWS-MO-GCNv2/FlaskApp.zip
unzip FlaskApp.zip
cd FlaskApp/
yum -y install python3-pip 
pip install -r requirements.txt
yum -y install stress
export PHOTOS_BUCKET=${SUB_PHOTOS_BUCKET}
export AWS_DEFAULT_REGION=
export DYNAMO_MODE=on
FLASK_APP=application.py /usr/local/bin/flask run --host=0.0.0.0 --port=80
```
