Hello I am trying to deploy my server to Railway App, but it gives me this error. Why do I need to change my listening to 0.0.0.0:$PORT?
Message: Looks like your app is listening on 127.0.0.1. You may need to listen on 0.0.0.0 instead.
npm WARN config production Use `--omit=dev` instead.
> server@1.0.0 start

(node:20) [MONGOOSE] DeprecationWarning: Mongoose: the `strictQuery` option will be switched back to `false` by default in Mongoose 7. Use `mongoose.set('strictQuery', false);` if you want to prepare for this change. Or use `mongoose.set('strictQuery', true);` to suppress this warning.
(Use `node --trace-deprecation ...` to show where the warning was created)
