I'm new to ruby on rails and app deployment, and I was trying to deploy a ruby on rails app to fly.io but kept on encountering an error. Bellow is the whole response after running fly launch in the app directory I was trying to deploy(the error is in bold letters):
C:\User\Desktop\deploy\DancEClass>flyctl launch

We're about to launch your Rails app on Fly.io. Here's what you're getting:

App Machines: shared-cpu-1x, 1GB RAM (most apps need about 1GB of RAM)
Postgres: <none> (determined from app source)
Redis: <none> (not requested)
? Do you want to tweak these settings before proceeding? No

I tried mannually attaching the database to my app as instructed in the error by running "fly postgres attach --app danceclass danceclass-db". It'll prompt the system to check for existing attachments but after a while it will just return an operation time out notice as shown bellow.
C:\Users\Desktop\deploy\DancEClass>fly postgres attach --app danceclass danceclass-db
