Better error when the database in unreacheable

[serv]

I noticed that when the database is behind a firewall, and the rails server cannot make any network request to the database, kamal setup fails by the rails server not starting.

There was no error message saying during the kamal setup command that indicates that. And when you try to go into the VM that hosts the rails container, and you do something like docker logs container-name, there's no logging at all.

Would it be possible to say something like connection timeout error or something to say the db:create failed because the server is unreacheable instead of being silent about this error?
