Customer unable to connect on port 5432, Postgres 10.7

Hello again Postgres friends,

Customer is unable to log in to a PG database on 5432 using a Windows client.
Output of my test sessions below, I think the problem may be lines 3 -
7 but no idea.
Ideas greatly appreciated!


Lines 1,2 PG Log entries
Lines 3-7 pg_hba.conf entries
Lines 8-10 postgresql.conf entries
Lines 11-12 Logging into the postgresql machine from a Linux machine
Lines 13-15 Successfully logged in, testing that SSH to the
linuxserver is successful
Lines 16-20 pguser successfully executes a query
