Heroku Database Connection Properties

I'm trying to perform a relatively trivial task: I want to connect to a Heroku database. I have created the database and have been issued credentials from the Heroku site. However, when I try to connect to this database using anything besides the terminal 'heroku' command line client, I get fatal errors or cannot connect errors.

The two tools that I tried to connect with outside of the Heroku terminal application are: Navicat and IntelliJ.

The error that I receive in Navicat when trying to connect to the database is:

could not connect to server: Host is down
    Is the server running on host "ec2-107-21-112-215.compute-1.amazonaws.com" and accepting
    TCP/IP connections on port 5432?

My connection settings are as follows:

Connection Name Heroku Dev Test

Host Name/IP Address ec2-107-21-112-215.compute-1.amazonaws.com

Port 5432

Navicat doesn't even seem to be making an attempt to connect to that hostname.

When I try to connect with IntelliJ, using the full credentials, I get the following error:

java.sql.SQLException: FATAL: no pg_hba.conf entry for host "75.168.4.146", user "rphbqggxeokuxl", database "dc008iqk0rq4j5", SSL off

Again, I'm using the credentials that the Heroku application provides me with when accessing my database on their website.

Has anyone ran into this Heroku connection issue before?

I also had the issue with the FATAL: no pg_hba.conf entry for host error message.

I solved the connection issue to my Heroku Postgres database by adding the following to my JDBC string: &ssl=true&sslfactory=org.postgresql.ssl.NonValidatingFactory.

Example

jdbc:postgresql://host:port/database?user=username&password=secret&ssl=true&sslfactory=org.postgresql.ssl.NonValidatingFactory

You will need the SSL option only if SSL is enabled for your Postgres database (which is the default).

Hint

If you want to check your database connection properties, then just run the following command with the Heroku Toolbelt: heroku pg:info --app your-heroko-appname (make sure that you have Postgres insalled to run this command in your terminal)

The pg:info command will also tell you that sslmode is set to require.

To test the database connection I recommend SQL Power Architect as it is the tool which I was using to check my solution.
