应用程序是 Rails 4.1.4，Ruby 2.1.2。
使用 sidekiq 3.2.6、redis 3.1.0、赛璐珞 0.15.2。除了连接到远程 redis 队列（弹性缓存）外，sidekiq 实现是默认的。
当处理某些事件时，我们使用 sidekiq 对外部 API 的调用进行排队。该 API 可通过 curl 从我们的应用程序所在的服务器访问。所有其他功能似乎仍按预期执行。此功能在当前的服务器实现/架构上已经工作了数周。
在成功部署（使用 Capistrano，通过 Jenkins）到 EC2 实例后，该实例位于弹性负载均衡器后面，自动扩展组 sidekiq 将不再连接（？）到弹性缓存。

我们重启了 sidekiq，重启了弹性缓存，重启了服务器，用 redis-cli 检查了 redis 队列，没有发现任何值得注意的地方。
正如暗示的那样，我们可以使用 redis-cli 连接到弹性缓存，但是，sidekiq/api从控制台使用，我们得到相同的结果SocketError
关于如何补救的任何想法？该应用程序在这一点上几乎无法使用。
谢谢！
