从API存储尝试API控制台时出现WSO2 APIM 2.0群集部署问题 [英] WSO2 APIM 2.0 Clustering deployment issue when try API console from API store

问题描述

我在一台服务器上部署了2个密钥管理器节点，2个发布存储节点，1个网关管理器节点和2个网关工作器节点，并部署了nginx来实现负载平衡.当我尝试通过API控制台访问API时，它报告了以下错误:

I deployed 2 keymanager nodes, 2 pub-store nodes, 1 gateway manager node and 2 gateway worker nodes in one server, and deployed nginx for load balance. When i try to access API via API Console, it reported below error:
