pgadmin4 won't use pgpass file

I have a .pgpass file for the postgres user to a specific database but pgadmin4 keeps asking for a password. Using psql from the command line works fine.

my pgpass looks like the following

localhost:5432:newdb:postgres:**********

Setting up a connection to the server in pgadmin4 I tried the following:

General (tab):

Name = newdb admin

Connection (tab):

Host name/address = /var/run/postgresql

Port = 5432

Maintenance database = newdb

Username = postgres

Advanced (tab)

Password file = /home/saultdon/.pgpass

When I hit Save it says,

Unable to connect to server:

fe_sendauth: no password supplied

Where I thought it would use the pgpass file but it doesn't.

So I enter a password in the Connection(tab) just to make the first connection.

I relaunch pgadmin4 and try to connect to the db but it asks for a password with the error message:

fe_sendauth: no password supplied

Please enter the password for the user 'postgres' to connect to the server - "newdb"

I'm not sure what else I need to do to get pgadmin4 to use this .pgpass file.
