EC2 Guide doesn't work

[bigxalx]

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?

Hi @bigxalx. So sorry for the late response, not sure how I missed this.

I just added some troubleshooting steps for this. I am thinking this may because port 80 is not open on your EC2 instance's firewall. https://github.com/cdr/deploy-code-server/tree/main/deploy-vm#troubleshooting

[bigxalx]

Thanks for the response. I made sure port 80 is open in my EC2 Security settings and the ubuntu firewall is disabled.

Here are the debug outputs:

There don't appear to be any bugs there 🤔

Are you able to visit the github oauth URL ok from the logs?

[cypressf]

I'm seeing the same issue. The bug is in this line:

[bpmct]

The --link service code-server uses is now deprecated unfortunately. We plan to add improved documentation using another service.
