成功验证后，Aperero CAS客户端抛出连接拒绝错误

Question

我们已经在wildfly-11.0中安装了cas-5.2.6（通过cas-overlay并使用underwow设置构建）

cas服务器运行正常。

我从git下载了示例cas-sample-java-webapp源，以使用cas客户端测试Java webapp。 我已将此cas-sample-java-webapp.war部署在同一容器（wildfly-11）下

https://github.com/cas-projects/cas-sample-java-webapp.git

登录后，日志中出现以下错误。 为org.aprero启用了调试级别，但无法找到错误的根本原因
