ServerSocketSelfCheckAddress
See parameter "ServerSocketSelfCheckInterval".
Here the TCP/IP address to connect to is specified. Default is 127.0.0.1 which is also the only sensible value, except your BCS is multi-homed, aka has multiple network interfaces.
The port number and the protocol BCS uses cannot be configured. If multiple listen ports are open, BCS has the usual priority: Secure WebSocket (TLS); if not configured then plain-text WebSocket; if not configured then SeplProtocol.
Possible values:
Default value: 127.0.0.1
