Answer 1

Have you set your mongodb MONGO_URL? the error auth fails means that the authentication details you've used may be incorrect.

Make sure you use something like MONGO_URL=mongodb://<user>:<pass>@<ip_address>:<port>/<database name> in the environmental variables with the correct username and password. You could test locally first to see your database works.
