Hi discourse community,

I am new to discourse and just testing the setup of discourse on an AWS ec2 instance following [discourse/docs/INSTALL-cloud.md at main · discourse/discourse · GitHub](https://github.com/discourse/discourse/blob/master/docs/INSTALL-cloud.md). However, I wasn’t able to spin it up. Here is problem I am having:

Before purchasing all the resources, I wanted to try out the website without a domain name, so I used Public IPv4 DNS of that instance as the hostname of discourse and to access the site, e.g. https://ec2\_ip\_address.us-west-1.compute.amazonaws.com/.  
I opened up the port 80, 443 on the instance via the security group, and verified these ports are accessible from public network (tested with python simple server).  
But I get “This site can’t be reached” in browser after starting the discourse server with `./discourse-setup` or `./launcher rebuild app`.

I tried the discourse doctor, and it returns

```plaintext
Discourse version at ec2-ip_address.us-west-1.compute.amazonaws.com: NOT FOUND
Discourse version at localhost NOT FOUND

```

I am not 100% sure if email setup is working, but I assume site accessibility is a separate problem with email.

Can anyone point me what is missing or how can I debug this issue?

thanks a lot!
