XMPP:使用Blabber的BOSH客户端无法通过代理获得响应

我正在尝试建立BOSH连接到端口7070上的openfire服务器，防火墙未被阻止，openfire正在积极侦听。如果没有代理，它可以在同一网络上运行openfire，但代理会出现以下错误：

java.io.IOException: java.net.SocketTimeoutException: Read timed out

下面是代码

BoshConnectionConfiguration boshConfiguration = BoshConnectionConfiguration
.builder().hostname("remote address").port(7070)
.proxy(new Proxy(Proxy.Type.HTTP,new InetSocketAddress("proxy address", 10015))).file("/http-bind/").wait(5000).build();
