Which one is on your host

ask the machine, not the registry

The registry says what 9090 is registered to. What is listening on it right now is decided by the host, and only the host can be asked. Each of these prints the process behind the socket.

linux
ss -ltnp | grep ':9090\b'
macos
lsof -nP -iTCP:9090 -sTCP:LISTEN
windows
netstat -ano | findstr :9090

On Linux and Windows the process name comes back with the socket; on macOS lsof needs sudo to name a process that isn't yours. Match what it prints against the 3 entries above.

A port number is not a service. Anything may listen on 9090 — what you actually met is decided by the host, not the registry. If a service is missing here, it belongs in the registry.
