@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 md5If 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.
