I tried to change localhost with paw.com so I changed it from etc/hosts folder. I entered in my react profect make a .env folder and write in this HOST='paw.com' . After that I tried to start the project with " npm start " and I got this error.

Attempting to bind to HOST environment variable: paw.com
If this was unintentional, check that you haven't mistakenly set it in your shell.
