Cannot Connect Remote Postgresql from a Oracle Cloud Infrastructure Jupyter Notebook
I'm currently testing Oracle Cloud Infrastructures technologies with Python and Postgresql (kindle see the figure herewith). So far, I managed to install my Cloud Jupyter Notebook, and ran some basic Python commands. However, when I tried to connect to my Postgresql DB or even upload csv any Data from my local machine raise this exception:
OperationalError: (psycopg2.OperationalError) could not connect to server: Connection refused
Is the server running on host "127.0.0.1" and accepting
TCP/IP connections on port 5432?
(Background on this error at: http://sqlalche.me/e/13/e3q8)
Just to mention that when reproduce the same test case on my local_host it works perfectly
