May you elaborate on that? What error is shown in the browser?

Is the process actually listening on the port? You can check that via a command like

# netstat -tpln | grep 3000

The fact that there is no output for netstat says that the application's daemon is not running. So, there is no application to connect to on the 3000 port.

Seems that application has not been started, or has been stopped right after start.

Can you share the project and IDE options (.idea folder in project's root)?
