Been following this guide step-by-step.
https://github.com/cdr/deploy-code-server/blob/main/guides/aws-ec2.md#deploying-code-server-on-aws-ec2

In the last step you're supposed to simply browse to the instance's public IP. This silently fails (Page loads forever, and after quite some time I get "Can't open this page because the server where it's located isn't responding").

Anything I can do to debug this?
