We have the database up, running functional and can hit it locally when we login to the Azure/RHEL instance. Everything works fine on the Linux box but connecting from a computer outside the Azure world we cannot get to work.
Dozens and dozens of articles later we are dead in the water and out of ideas.
Connecting with sqlplus, TOAD or SQL Developer doesn't work so we are perplexed and displeased with the lack of documentation around this. The articles that are out there are plentiful for "select" scenarios but nothing realistic as to troubleshooting.
Here is one of the dozens of articles we are talking about. We need help determining the issue and not another install (3 so far that are not successful)
Oracle works. It is running. We need to troubleshoot connectivity to it.
Any help would be greatly appreciated
