redis cli工作-两者都不是任何nodejs redis客户端

我遵循了以下指南：https://redislabs.com/blog/redis-on-windows-10/ 安装以下组件：windows子系统、ubuntu和redis服务器，一切都通过ubuntu终端和windows中的redis cli运行。我可以设置和获取值。但是我的nodejs客户端不工作/无法连接（只有第一次？）。
我已经安装了以下npm redis客户端：redis(https://www.npmjs.com/package/redis).

const redis = require("redis");
const client = redis.createClient();

client.on("error", function(error) {
  console.error(error);
});

client.set("key", "value", redis.print);
client.get("key", redis.print);

第一次它成功了（它可以设置和读取名为“key”的键）！但从那以后就再也没有了！？我试过关闭和打开ubuntu终端，重启redis服务器等，但似乎没有什么帮助。redis cli在ubuntu终端上一直工作——只有nodejs客户端突然不工作。
我还尝试安装另一个客户端：https://www.npmjs.com/package/ioredis 但问题依然存在，而且是一样的。我和这个客户是这样联系的：

const Redis = require("ioredis");
const redis = new Redis({
    port: 6379, // Redis port
    host: "127.0.0.1", // Redis host
    family: 4, // 4 (IPv4) or 6 (IPv6)
    db: 0,
});

// ioredis supports all Redis commands:
redis.set("foo", "bar"); // returns promise which resolves to string, "OK"

// Or ioredis returns a promise if the last argument isn't a function
redis.get("foo").then(function (result) {
    console.log(result); // Prints "bar"
});

再说一次，它第一次与第一个redis客户端一起工作，我没有设置任何身份验证/凭据。。。
我没有更改默认conf文件中的任何一行。
我刚刚尝试过安装ubuntu20.04（在运行18.04之前）并再次从头开始安装redis，但结果是一样的：redis cli可以工作，但nodejs客户端都没有（现在甚至不是第一次）。
在我捕捉到“重新连接”和“连接”事件之后，它抛出异常，然后在循环中一遍又一遍地运行这些步骤。所以它似乎可以连接，但有什么东西会马上断开它？
第六章。我得到这个错误消息（npm:redis）：

Error: read ECONNRESET
    at TCP.onStreamRead (internal/stream_base_commons.js:209:20) {
  errno: -4077,
  code: 'ECONNRESET',
  syscall: 'read'
}

    errno: -4077,
    code: 'ECONNRESET',
    syscall: 'read'
  }
}

第6b条。或者现在我在使用npm:ioredis:

[ioredis] Unhandled error event: Error: read ECONNRESET
    at TCP.onStreamRead (internal/stream_base_commons.js:209:20)
    at TCP.callbackTrampoline (internal/async_hooks.js:129:14)
