Create-react-app: Development server on port 80 does not start

[levrik]

Description

I was trying to start a app on port 80 I currently working on through WSL.

Expected behavior

It just works fine.

Actual behavior

I started it with yarn start. Executing this command in a Windows command line or a PowerShell in the same directory is working fine. Changing the port to something else resolves the issue in WSL too.

Environment

Run these commands in the project folder and fill in their results:

1. npm ls react-scripts (if you haven’t ejected): 1.0.6
2. node -v: 6.11.0
3. npm -v: 3.10.10

Then, specify:

1. Operating system: WSL under Windows 10 Version 1703

[Timer]

Did you try using sudo? Any port under 1024 generally requires administrative permissions.

@Timer Ah didn't know that. Thanks. Is working with sudo now.
