More recent resolution:

1. cd ~/../../etc (go to etc folder in WSL).
2. echo "[network]" | sudo tee wsl.conf (Create wsl.conf file and add the first line).
3. echo "generateResolvConf = false" | sudo tee -a wsl.conf (Append wsl.conf the next line).
4. wsl --terminate Debian (Terminate WSL in Windows cmd, in case is Ubuntu not Debian).
5. cd ~/../../etc (go to etc folder in WSL).
6. sudo rm -Rf resolv.conf (Delete the resolv.conf file).
7. In windows cmd, ps or terminal with the vpn connected do: Get-NetIPInterface or ipconfig /all for get the dns primary and
secondary.

What is Erlang?
  "Erlang is a declarative, dynamically-typed, functional, concurrent, distributed and fault-tolerant programming language with garbage collection and code hot-swapping built into its runtime."

"Let it crash!"
  - Erlang was designed to build software that "never" stops, i.e. at least 99.999% uptime.
  - Erlang programmers concentrate on coding for the correct case and crashing on failure.
  - Robustness is achieved by having programmers concentrate on processes and the interactions (or messages) between them.
  - Early error detection/recovery and the use of concurrent programming techniques lets you build fault tolerant systems.
  - COP: Concurrency-Oriented Programming

Embedded mode

Purpose

Embedded mode allows you to insert Ranch listeners directly in your supervision tree. This allows for greater fault tolerance control by permitting the shutdown of a listener due to the failure of another part of the application and vice versa.
