psql could not connect to server connection refused error when connecting to using -'postgresql,ubuntu,psql,centos7'


psql could not connect to server connection refused error when connecting to  using -'postgresql,ubuntu,psql,centos7'

I am trying to connect to a postgres database installed in a remote server using the following command:

psql -h host_ip -U db_username -d db_name

This the error that occurs:


  psql: could not connect to server: Connection refused
      Is the server running on host "" and accepting
      TCP/IP connections on port 5432?



Postgres installed version is 9.4.
Host operating system : Ubuntu 15.04
Client operating system : Centos 7


I already tried the following but the issue remains unresolved:


Edited pg_hba.conf file to include



  host    all     all     0.0.0.0/0  md5



Edited 'postgresql.conf' and changed the listen parameter to



  listen_addresses='*'



Restarted postgres service.
Disabled firewall and iptables on host and client.
I checked by running the psql command locally and it worked.
I tried the second solution given in this question. Running nmap gave me the following output:


Starting Nmap 6.47 ( http://nmap.org ) at 2015-09-07 18:08 IST
Nmap scan report for 10.17.250.250
Host is up (0.0000040s latency).
Not shown: 997 closed ports
PORT   STATE SERVICE
22/tcp open  ssh
25/tcp open  smtp
80/tcp open  http

Am I missing something. Hope someone can help.
