Unable to access forwarded ports

[dcb99]

Running an app in a container in Coder and attempting to access the app by forwarding a port to my local machine, in this case, 8080, results in an connection refusal error

This isn't an issue in VS Code, and I know JetBrains just released a patch that was supposed to allow port forwarding from containerized projects. Otherwise, using WebStorm attached to a Coder instance seems to be fine, there are no performance issues. My local machine is a MBP running Sonoma 14.6.1 and WebStorm 2024.3.1, and the latest version of JetBrains Gateaway.

The forwarding is entirely provided by JetBrains, not our plugin (in fact our plugin only runs in Gateway and not in the client nor remote IDE at all), so there is nothing we could do unfortunately.

My guess is that if the app is inside a container, it needs to listen on 0.0.0.0 and not localhost, otherwise it will not be accessible outside the container. Also the container needs to forward 8080 to the host. Maybe that patch you mentioned is supposed to work around these restrictions, but is not released yet or is not working correctly? I think the VS Code extension does exec into the container or something to make this work automatically, but I am not 100% sure how it works.
