When setting up a server, you must check that the Firewall on the server is set to allow the incoming ports for the database connections that you have created.
For example, in the default SSCloudServices.config configuration file the ports 804 and 805 and are set as operative. If you have a firewall you must set these ports as enabled for inbound traffic.
For information on creating the Inbound Rule to identify the ports you have specified in the config file (the 'Sparx Systems Cloud Services' rule in the illustration), see the Microsoft Windows online topic Create an Inbound Port Rule.
Note: A common cause of failure is that other services or programs are already using the allocated ports. This is especially likely when using the default http (80) and https (443) ports. Check that no other services are using the allocated ports.
