一、该问题的重现步骤是什么？

1. boot项目已经集成Cloud,已经注入到nacos,共用一个网关

boot项目请求feign时的方法：

2. bladeX接收请求：

二、你期待的结果是什么？实际看到的又是什么？

期待的结果可以正常访问feign接口，现在目前的状态是，接口大部分可以请求成功，偶尔会出现请求失败，出现失败问题时返回的http code还不一样，错误信息也不一样，具体内容如下边提供的堆栈信息

三、你正在使用的是什么产品，什么版本？在什么操作系统上？

我使用的是BladeX-Boot：4.2.0.RELEASE； BladeX：4.2.0.RELEASE，操作系统：CentOS Linux 7

四、请提供详细的错误堆栈信息，这很重要。
