 Connections to your Azure Database for PostgreSQL server communicate over port 5432

Connections to your Azure Database for PostgreSQL server communicate over port 5432. When you try to connect from within a corporate network, outbound traffic over port 5432 might not be allowed by your network's firewall. If so, you can't connect to your server unless your IT department opens port 5432.
