no pg_hba.conf, just will not work. I have located and tried changing it many times

Question

I have no pg_hba.conf error with Heroku Postgres. I have searched all over especially on here and tried many of the users suggestions. I have tried changing the pg_hba.conf file to pretty much all the different settings that a lot of the users on here have suggested, with no luck. My database is returning the correct info and still I can't get my app to work.

the error is:

2021-03-09T15:58:42.393656+00:00 app[web.1]: error: no pg_hba.conf entry for host "34.203.11.205", user "XXX", database "XXX", SSL off

My pg_hba.conf file is:

# TYPE  DATABASE        USER            ADDRESS                 METHOD
# "local" is for Unix domain socket connections only
local   all             all                                  trust
# IPv4 local connections:
host    all             all             127.0.0.1/32            trust
# IPv6 local connections:
host    all             all             ::1/128                 trust
Allow replication connections from localhost, by a user with the
replication privilege.
local   replication     all                                     trust
host    replication     all             127.0.0.1/32            trust
host    replication     all             ::1/128                 trust

I have added:

host all all 192.168.0.0/24 trust/md5 -- no luck
host all all 0.0.0.0/0 trust/md5 --- no luck
host (database info) (user info) (ip address) trust/md5 -- no luck
local all all 0.0.0.0/0 trust/md5 -- no luck

I have change the Postgresql.conf file to have #listen_addresses = '*'

I have tried to change the connection string to have ssl: true

Can someone please help, it works in development mode, just not when I upload to heroku.

Answer 1

just remember, PostgreSQL does not lie:p

For IPv4 you only have

# IPv4 local connections:
host    all             all             127.0.0.1/32            trust

Means, you only expect local connections. Just add the scope for the IP "34.203.11.205"

for example:

host    all             all             34.203.11.205/32            md5
