老师请问下，我在windows上配置redis的host为装了redis的服务器公网ip，连接不上，是什么原因？视频中我看用的是127.0.1，这样是不是连接的本地windows的，是怎么连上的，不是因该用公网ip连接服务器吗？ 感谢解答！！
下面是错误：
Error creating bean with name ‘enableRedisKeyspaceNotificationsInitializer’ defined in class path resource [org/springframework/session/data/redis/config/annotation/web/http/RedisHttpSessionConfiguration.class]: Invocation of init method failed; nested exception is org.springframework.data.redis.RedisConnectionFailureException: Unable to connect to Redis; nested exception is io.lettuce.core.RedisConnectionException: Unable to connect to 39.101.141.44:6379
