我正在开发一个产品，我们有一组后端服务器，我们建立了网络套接字连接以传输数据，为此我使用 AndroidAsync（V2.1.6）客户端库那。这些服务器在不同版本的tomcat上运行。
从android方面来看它工作正常并且websocket已在所有服务器上建立，直到今天，但现在我们无法在其中一个服务器中建立连接。
困境是android端和服务器端的代码也没有变化。相同的代码适用于所有服务器，而不适用于这一个特定的服务器。
经过几个小时的挖掘后，我们发现连接失败的服务器最近更新了最新的tomcat配置和相同的 tomcat版本（V8.0.23）我们没有使用所有的其他服务器。其中一个服务器人通过分析 change-log 来了解tomcat中的web-socket有一些变化。
我已经做了一切探索和摆脱这个问题，但我无法解决这个问题。
尝试使用该服务器上的AndroidAsync进行连接时服务器的堆栈跟踪：
