ERR_CONNECTION_REFUSED when building employee directory app

Question

I'm a beginner going through the tutorial to create the "Employee Directory App" from the AWS Technical Essentials program. I've gone through each step in detail, successfully launching my instance on EC2. When copying the public IP in a new browser tab as shown in the video, I get an ERR_CONNECTION_REFUSED error.

I've double checked everything (Security Groups, Permissions, etc...) and everything matches what was done in the video. Any idea what may be causing the error?

Thanks!

Answer

you might want to check the user data script that should install the application on the ec2 instance, and whether it is compatible with the AMI you are using, you can connect to the ec2 using instance connect and then try to run the script manually with sudo permissions and see if it gives any errors

HI there, running through the same training.
It worked for me with http:// but not for https://. So try if http works.

any suggestions?

Thanks

Answer

I have the same problem. http works fine but with https I've got the following message from my browser:
*This site can’t be reached18.101.32.181 refused to connect.*

Where  *18.101.32.181* is the public IP address asigned.
Apparently my security groups are correctly configured:

I'd appreciate if someone can help with this.

Please refer to the following document to confirm that the problem is not on the browser side.

Also, see if you can connect to the EC2 IP address from your computer with the following command.  
If you are able to access the site with the following commands without any problems, the problem may not be on the EC2 side, but on your computer.  
```
curl http://EC2 IPaddress
```
