PostgreSQL version: 11.1
Operating system:   Windows 10
Description:

I am trying to connect a Postgres database which resides in a docker
installed on Ubuntu virtual machine. Following exception is being thrown on
the console.

    org.postgresql.util.PSQLException: FATAL: no pg_hba.conf entry for host
"10.1.X.X", user "usrXXX", database "dbXXX", SSL off

After going through various posts, I realised that I have to update
pg_hba.conf file. I have modified the file to include the following
settings.

   host dbXXX usrXXX 10.1.X.X/32 trust

*(Note I tried with md5 as well.)*

I verified the postgres database settings through `psql` and executed
commands as specified in this
post(https://dba.stackexchange.com/questions/161104/pgadmin-postgresql-no-pg-hba-conf-entry-for-host).
This verified that I am editing correct file. To take a step further, I also
verified the entry through pgAdmin (*pgAdmin is installed locally on
postgres host*) and found the following query is returning records as
entered in pg_hba.conf

    table pg_hba_file_rules;
