npm run dev and connection refused

Hi, I just created a Remix app with the indie stack. Everything is setup but when I run npm run dev, it doesn't seem to listen to port 3000, even if I get this success message:

Loading environment variables from .env
Watching Remix app in development mode...
Done in 239ms.
💿 Built in 379ms
Remix App Server started at http://localhost:3000 (http://DESKTOP-5N24D9N:3000)

When trying to open this address with a browser, I get "Connection Refused".

I even tried with wget:

nicolas@DESKTOP-5N24D9N:~> wget localhost:3000
--2022-05-30 10:35:06--  http://localhost:3000/
Resolving localhost (localhost)... 127.0.0.1
Connecting to localhost (localhost)|127.0.0.1|:3000... failed: Connection refused.

Here's the netstat output. Nothing seems to listen on port 3000:

nicolas@DESKTOP-5N24D9N:~> netstat -lp

Setup:

Windows 10 + OpenSuse Tumbleweed on WSL 2. The remix app is running in WSL.

FYI, running another legacy NodeJS app running Express server on port 3000 is fine and accessible without problems.

I fixed it by adding the HOST environment variable to the command: HOST=127.0.0.1 npm run dev
