我已经在Heroku上安装了Proximo插件,当我将命令添加到现有命令时,我从Java获得了BindException.这是我的prepended命令的外观:web: bin/proximo sh target/bin/webapp并且一旦我删除Proximo part(bin/proximo),应用程序就会启动而没有错误.
这是完整的堆栈跟踪.我错过了什么？

我有一个简单的节点代理,我已经添加了proximo来为API使用白名单.它以前工作过,但是按照教程我现在在我的日志中得到这个:
2014-08-19T16:23:21.376311+00:00 heroku[router]: at=error code=H12 desc="Request timeout" method=GET path="/?url=http://www.google.com" host=warm-cliffs-7633.herokuapp.com request_id=ecf77eea-a027-4115-86ff-5acf527c7333 fwd="82.24.137.140" dyno=web.1 connect=1ms service=30001ms status=503 bytes=623
如果我尝试访问该页面,我收到一条错误消息,但如果没有从代理请求URL,页面工作正常.
文档不多,我不确定这在我的Procfile中是否正确:
web: bin/proximo node proxy.js
我需要从 Heroku 访问具有 IP 白名单的服务，因此需要 HTTP 代理。
我配置了 Proximo 插件，并且有一个看起来大约像这样的代理 URLhttp://proxy:secret-key@proxy-0-0-0-0.proximo.io
在 Savon 中，我尝试像这样配置代理：
client = Savon.client(wsdl: my_wsdl, proxy: "http://proxy:secret-key@proxy-0-0-0-0.proximo.io")
但是当我提出请求时：
client.operations
我收到代理错误：

不过，如果没有代理选项，一切都可以正常工作。
我在 Heroku 上运行 Ruby on Rails 应用程序，我的数据库位于其他地方，只能使用某些列入白名单的 IP 访问它，但由于 heroku 不提供动态 IP，我想使用 proximo。
请帮助我如何从 heroku 使用 proximo 连接到远程数据库。
