./alloydb-auth-proxy projects/<projects_name>/locations/<instance_location>/clusters/<cluster_name>/instances/<instance_name> --credentials-file <path_to_key> --port 5432 --address 0.0.0.0

From the comments:

The problem is accessing from local won't work. AlloyDB currently doesn't implement a Public IP connection, so the only way to connect to it is from within the same VPC (cloud network) as the AlloyDB cluster itself. That's why connecting from a GCE instance on the same network works while connecting from the local machine does not.
