Unable to connect to Postgresql on a server

  • 772

On Digital Ocean I'm able to connect to Postgresql:

psql -d my_db -U my_name

for which it asks me a password and I get in successfully. But from my local computer I'm unable:

psql -d my_db -U my_name -h x.x.x.x

Nothing happens at all. Here's my /etc/postgresql/9.4/main/pg_hba.conf

# 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                                     md5
# IPv4 local connections:
host    all             all             0.0.0.0/0                md5
# IPv6 local connections:
host    all             all             ::1/128                 md5
# Allow replication connections from localhost, by a user with the
# replication privilege.
#local   replication     postgres                                peer
#host    replication     postgres        127.0.0.1/32            md5
#host    replication     postgres        ::1/128                 md5
ssh remote-access postgresql

    Check and make sure postregsql is listening on your interface IP (not just 127.0.0.1).

    ss -ltn

    If not, modify the listen_addresses to * or the IP you want. These settings should be in postgresql.conf file generally located in the postgresql data directory.
