WSL2 - Unable to access localhost:3000 from Windows browser

[cvkmohan]

Please fill out the below information:

• Your Windows build number: (Type ver at a Windows Command Prompt)
  Windows build 18945.
• What's wrong / what should be happening instead:
  I have installed WSL2 using the guide https://docs.microsoft.com/en-us/windows/wsl/wsl2-install
  After installing, I have installed ruby and rails in the Linux local file system.
  The installation has visible speed change compared to wsl1 and went smoothly.
  Now, when I try rails s - It shows tcp:localhost:3000 has Puma server listening, but, when I type localhost:3000 in the Chrome browser in Windows, I get nothing.
  I tried rails -b 0.0.0.0 s also, to bind the server, still nothing happens.

Unsure what happened. I got 18950 build today. Once I have upgraded and reinstalled WSL2, now, when I tried rails -b=0.0.0.0, it started working.
WSL2 has an order of speed difference when compared to WSL1. Thanks for all the effort.

In my environment

wsl2 react server localhost;3000 is OK
I can open react page.

wsl2 rails server localhost:5000 is NG
I can't connect my rails API.

I am sorry I can't speak English well.
