Postgresql – no pg_hba.conf entry for host “10.1.1.91”, user “user” database “testing”, SSL off

I've come across different versions of this same issue on stackoverflow and on this forum. I've tried the recommendations posted on these forums but I am still unable to connect to a database. I've run out of leads to try and I'm hoping someone can explain to me what is happening and why I am unable to connect. The context of my question follows:

I pg_dumped a database on a server host named test-crawl-1 and have pg_restored the database onto a new server host named test-qa-db where it resides with 4 other databases. I've changed the database. yml file to look like this:

testing:
  db_host: test-qa-db
  db_port: 5432
  db_name: testing
  db_user: user
  db_pass: password

Next, because of the error I'm receiving I tried the following, I sshed into a VM named test-utility-1 and modified the pg_hba.conf file there to reflect the following:

# Database administrative login by Unix domain socket
local   all             postgres                                peer

# TYPE  DATABASE        USER            ADDRESS                 METHOD

# "local" is for Unix domain socket connections only
local   all             all                                     peer
# IPv4 local connections:
host    all             all             127.0.0.1/32            md5
# IPv6 local connections:
host    all             all             ::1/128                 md5

#Trying to fix the SSL error
host    all             all             0.0.0.0/0               md5

Then I tried this:

# Database administrative login by Unix domain socket
local   all             postgres                                peer

# TYPE  DATABASE        USER            ADDRESS                 METHOD

# "local" is for Unix domain socket connections only
local   all             all                                     peer
# IPv4 local connections:
host    all             all             127.0.0.1/32            md5
# IPv6 local connections:
host    all             all             ::1/128                 md5

#Trying to fix the SSL off error attempt 2
 local  all      all   (test-utility-1 address)10.1.1.1/32      md5

And then I tried to implement in the postgresql.conf file:

postgresql.conf

listen_addresses = "*"

I pretty much tried that line with the above variations but I have still yet been able to make it work. Is there anything that I'm missing. I'm not sure what else is there to try. Help would be appreciated thank you.

————EDIT———-

I forgot to mention that I also hard coded the database, user, and Ip address into the corresponding fields but the SSl but the error still persists.
