    Cant connect to Oracle DB on Amazon EC2 (firewall is already open for 1521)

    Ahsan Shah
      I am unable to connect to a Oracle DB instance on Amazon EC2 using SQL Developer. I confirmed that the listener is up...port 1521 is open through the EC2 firewall, and that the DB is accessible from the EC2 server itself (via remote desktop).

      Anyone know what the issue may be? I can successfully SSH, and also use HTTP/HTTPS on that server so it seems only to be an issue with connection to the Oracle DB.

      Thanks in advance for your help.
