unable to connect to database using multiple users

[Kumar6295]

We are using pgbouncer for connection to database.
we configure same database with different users but we are unable to connect to database ,it is giving below error.

ERROR

psql: error: ERROR: client_login_timeout

configuration

databases:
postgres_db:
host: localhost
port: 7778
user: postgres
dbname: postgres
auth_user: postgres
test_db:
host: localhost
port: 7778
user: postgres
dbname: test_db
auth_user: insight_user
portal_db:
host: localhost
port: 7778
user: postgres
dbname: test_db
auth_user: portal_user

users: {
postgres: postgres,
insight_user: X!q6DoGKc@iN,
portal_user : portal_user
}

psql -h localhost -p 5432 -d portal_db -U portal_user
password: portal_user
psql: error: ERROR: client_login_timeout

psql -h localhost -p 5432 -d test_db -U insight_user
password: X!q6DoGKc@iN
psql: error: ERROR: client_login_timeout

In users we need to mention auth_user and one of the password for user right??
Their no database password for particular user .

How we can connect database with multiple users??
