2377425 - What ports need to be open in a firewall for connection with SAP Cloud Connector and what IP Addresses at SAP does it connect to?

• Which ports need to be open in a firewall so that SAP Cloud Connector (SCC) can communicate with the SAP Business Technology Platform (BTP)?

• SAP Cloud Connector (SCC) is installed as High Availability. It is important to know which ports need to be open in a firewall to allow the master* and shadow* instances to communicate with each other.

• Whether SAP Cloud Connector (SCC) needs to be used when an on-premise application needs to connect to an application in BTP which is accessible via the internet?

• The following error may appear in the SCC web page:

               - "CONNECT_FAILED / Failed to connect"

               - "#ERROR#com.sap.scc.rt#http-bio-8443-exec-9# #Tunnel Connect Failed java.nio.channels.UnresolvedAddressException"
