我无法弄清楚这一点。我有芹菜烧瓶应用程序，并在Ubuntu 16.04上使用Redis作为代理。它在最近几天工作正常，今天它突然发出以下异常。在我的OSX上本地工作正常。在ubuntu虚拟服务器上失败。

我猜它会在2秒后重试并再次失败并出现相同的异常。更令人困惑的是redis-server启动并正常运行。 redis-cli ping工作。此外，我打开了redis-cli并试图获得芹菜工人应该添加的值。那些也是可以得到的。顺便说一句，我刷新服务器重启时的所有值。因此，当我重新启动服务器时，它会相应地更新值。我怎么弄清楚出了什么问题？
我没有对redis-server配置文件进行任何更改。各种方式一直运作到昨天。
编辑：令人惊讶的是我收到此错误＆＃39; ConnectionRefusedError：[Errno 111]连接被拒绝＆＃39;在一些陈述被执行之后。所以基本上它连接到redis db，放入值然后失败。什么？
