I'm having some issues with my EC2 launch template instances. While I can SSH into them without any problems, I can't connect through the public IP address using my browser. I even created a launch template based on a working EC2 instance, but I'm still facing the same problem. It's quite puzzling! Does anyone have any insight or suggestions?

If you're using a load balancer with your EC2 instances, make sure you've configured the inbound rules for the load balancer's security group as well. Sometimes, it's the little things that trip us up!
It sounds like the issue could be related to your security group settings. You might want to check if the security group is allowing traffic on the necessary ports (80 for HTTP or 443 for HTTPS). Are you able to see if the connection times out or fails instantly? That might give more clues to the problem.
I'm using the same security group as the working instance, and I followed the tutorial closely. It's confusing because I can SSH in just fine, but the browser just times out.
I see, that can be tricky! Maybe double-check if any of your firewall settings on the local machine could be interfering.

I actually recreated the entire setup this morning, including the SGs and the load balancer, and it's finally working now! I was confused because I thought using a template from a working instance would make everything seamless.
