docker or something, resets connection on port 5173

laravel logs don't show anything regarding this. Opening network tab on firefox, i clearly see "app.js", "app.css" and a file named "client" aren't loading. apparently, there's this message: "NS_ERROR_NET_RESET" which means the server reset the connection. (https://stackoverflow.com/questions/77306379/ns-error-net-reset-in-firefox)

First, I'll check my error logs like this:

docker logs -f 69606e53f326 1>/dev/null
