Dev enviroment can't connect to localhost:3000

I started dev env with webpack (live update) and i’m getting can’t connect to localhost:3000. Any hints why would that happen?

Sorry Im not a subscriber, so I cant really help, but maybe @Deadpool198 or @PeterPalov may be able to help?

You don’t need to be a subscriber to use dev env

Yea, I have never really used it before so I cant really help

Looks like I’ll need to debug by myself… I’m awful at hosting web apps. Help still needed

If starting through docker:

This if just preview (not webpack):

Can the problem be related to lodash installation?

Maybe… I’m setting up dev env for the first time

I did the exact same thing and had the same problem, as far as I can remember. Go here:
The devs will help you. And if you scroll up through the messages (there aren’t very many), you’ll find my (and other peoples’) problems, which I think may be quite similar to yours.

I don’t even understand what is dev eviroment. So I can’t help.

I’d love to learn to hack codecombat, but I have windows, and according to all other topics about this stuff, it’s really hard without mac. I tried, but it requires a bunch of stuff that I don’t know how to use and may help me get viruses as far as I know.
