How do I check this port?
Test-NetConnection SERVER -Port 6379
On Linux, nc -vz SERVER 6379 checks TCP connectivity only. A successful TCP connection does not validate the application, authentication or TLS configuration.
Port-to-service mappings are common conventions. Applications can use a different configured port; confirm the actual service and transport.
