I want to conenct a postgres db from local computer. I tried connect with psql given following this connection string.

bash
psql postgres://USERNAME:PASS@db.shuttle.rs:5432/db-MYAPP

It's occurs an error.

psql: error: connection to server at "db.shuttle.rs" (X.X.X.X), port 5432 failed: FATAL:  password authentication failed for user "user-MYAPP"

How can I connect?

Looks like wrong password was used? Check to see your pw didn't change between deployments

Now, I deployed an app again. So, It's new connection string worked. Thanks very much.
