あ、statusには
*** FATAL CONFIG FILE ERROR (Redis 6.0.1) ***
redis.service: main process exited, code=exited, status=1/FAILURE
Failed to start Redis persistent key-value database.
とかも書いてます

Error: connect ECONNREFUSED 127.0.0.1:6379
at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1187:16)
errno: -111,
code: 'ECONNREFUSED',
syscall: 'connect',
address: '127.0.0.1',
port: 6379
とか出ます

どっちもダメみたいです
