The Occurence

I'll be coding away, testing something, refactoring another or trying to figure out things on a dev server. I'll finish, then when I come back some time later and try to run a dev server and I am met with this error:

listen EACCES: permission denied 0.0.0.0:3000

This is on Windows

What Causes It?

I am actually stumped myself as:

1. I have no clue what causes it and
2. I don't know how to trigger it.

Most of the explanations point to something to do with Docker, but I do not have Docker installed. It must be something else that I can't seem to pinpoint.

The Solution

The best solution I have found to resolve this error is as follows:

• Open PowerShell as Admin and stop winnat with the command below:

net stop winnat

• Start winnat again with the command below:

  net start winnat

I have encountered this error enough times that I know the exact search term to find this solution. So rather than Googling the same thing over and over, I'll keep it here for quick access.

Might you know exactly what triggers it and how to avoid it in future? I would be very grateful for any explanation that makes sense.
