      Hi, I'm having issues setting up FusionAuth on my EC2 instance. FusionAuth is unable to connect to a PostgresQL database on the same box.

      System information:
      Ubuntu 18.04.5 LTS
      PostgreSQL 12.5

      Database is running on the default port (5432). I created a database with the same name as the user I usually SSH into the box as. The user is a database superuser. I've confirmed that I can run psql as this user and connect to the database and run commands.

      In the FusionAuth maintenance mode page, I have the following settings:

      • Host: localhost
      • Port: 5432
      • Database: <name of the superuser> (already created)

      I also specified the superuser credentials and verified that they are correct. Additionally, I also left the generated FusionAuth user credentials in place.

      When I try to Submit the form, it says:
      Unable to connect to your database using either the superuser username and password or ordinary username and password you provided. Please verify your connection information. If it is correct, make sure the database is running before continuing.

      I've verified all of the above is correct, but still no dice.

      I stopped the FusionAuth process, deleted the logs and started fresh. Here are the complete logs from an isolated attempt to start FusionAuth and submit the maintenance mode information once:

        @tarun-verghis Ensure your database is listening on a valid IP and that you have the ability to connect to it using username/password. This is usually configured in the pg_hba.conf file and requires a line like:

        host    all             all             127.0.0.1/32            md5

        If you only have lines that say trust then FusionAuth won't be able to connect since it doesn't support local sockets or local connections.
