I installed Ubuntu 14.04 on Azure recently. Have been trying to connect to PostgreSQL but the server refuses the connection. I checked and confirmed that it was online. I also tried changing the settings to trust on pg_hba.conf and I also edited the Postgresql.conf file to listen to all addresses. Furthermore, I checked my firewall settings on Windows and allowed Pgadmin 4 to go through. Despite following all the instructions in this question (Unable to connect PostgreSQL to remote database using pgAdmin), I was unable to connect. What should I do?

I'm guessing that postgres server is installed on Ubuntu system and you are trying to connect it from your local system using pgAdmin4?Murtuza Z– Murtuza Z2017-06-02 08:24:04 +00:00Commented Jun 2, 2017 at 8:24

I once had such issue with pgAdmin4 on win 10. Here is the step I took to connect to my remote server
first enable port 5432 to pass through firewall in ubuntu:
sudo ufw allow 5432/tcp
Then edit your postgresql.conf file and add
listen_addresses = "*"
file can be found at /etc/postgresql//main/postgresql.conf
Proceed to edit pg_hba.conf and add
host all all 0.0.0.0/0 md5
Now stop the server using/etc/init.d/postgresql stop and restart /etc/init.d/postgresql start
You should be able to connect now. However, you can allow pgAdmin4 to pass through the windows firewall
control panel > System and Security > Allow an app through windows firewall
You can also allow same app for any antivirus you've installed
Note: If you still cannot connect, you can reset your postgres user's password NOT linux default user
sudo -u postgres psql postgres
# \password postgres
Enter new password
Then use this new password to connect your pgAdmin4 using
postgres as Maintenance database
postgres as username
then new password
Hopefully, you should be able to connect

Enable your postgresql server to start at boot
sudo systemctl enable postgresql
Start your postgresql server
sudo systemctl start postgresql
verify your postgresql server is running:
sudo systemctl status postgresql
