Client can't connect to server in WSL environment

[MaksimMyshkin]

Environment: Windows 10 with WSL2. codecrumbs installed in WSL2 OS.

How to reproduce:

• start codecrumbs in wsl console
• open browser and go to localhost:2018 (in Windows)
  After that client just hanging out. Console contains the message: "WebSocket connection to 'ws://127.0.0.1:3018/' failed: Error in connection establishment: net::ERR_CONNECTION_REFUSED".

How to solve:
It's need to just use localhost in url instead of 127.0.0.1. Otherwise ports from WSL are not accessible.
