Wso2 API网关集群 - DataEndpointAuthenticationException：无法为ssl借用客户端：//10.0.0.111:9711

Question

我有一个wso2网关集群，并且都在一个APIM节点中。当我使用以下命令./wso2server.sh -Dprofile=gateway-manager命令启动网关管理器节点时，它会给出以下错误。

根据我的理解，我已将API网关管理器配置为TrafficManager节点，该节点是在另一个VM上单独托管的一体化节点（IP：10.0.0.119）

以下是我在API网关管理器节点的api-manager.xml中所做的配置更改。
