I have been following youtube guide to learn terraform and have followed each steps. After running terraform apply it was able to setup everything as expected. I have verified this on aws console. But while trying to access the public ip it is saying connection refused.
Below is the content of my main.tf file.

CodePudding user response:
You are missing -y
in your user data, so your user-data will just hang for confirmation. It should be:
sudo apt install -y apache2
