Vapor cloud deploy failed: Sockets Error: Failed trying to connect to http://redis.eu.vapor.cloud:6379

我使用 swift 包管理器手动设置 Vapor 项目。我遵循文档。 它在我的本地机器上构建并成功运行,用于调试和发布构建。

但是未能部署到蒸气云:

Error: Sockets Error: Failed trying to connect to http://redis.eu.vapor.cloud:6379

Identifier: Sockets.SocketsError.connectFailed

Here are some possible causes: 
- The hostname or port is not valid    

任何人都知道是什么导致了这个错误?

我打开了一个 issue on GitHub 并得到了这样的回复:

Hi, It's usually caused by either a firewall, or a proxy preventing connection to our Redis cluster, that is providing log feedback to the terminal.

We have seen it a couple of times, and are working on allowing to see log output in the dashboard, for these kind of situations :)

仍然找不到解决方案。
