Unhandled exception, type=NullPointerException

[阿政]

部署玩ocp和添加完主机,想要连接集群却是失败连接集群zhutang失败, 请检查该集群sys租户root用户凭据是否正确，sys租户白名单设置是否正确，以及网络是否连通

凭证正确,白名单没有设置,网络也是通的,不知道什么原因,现在报这个错误Unhandled exception, type=NullPointerException

[mark2022]

查一下对应报错时间范围的obproxy_error.log 日志，应该有报错详情信息

[阿政]

路径是?

[旭辉]

发下OCP版本
以及包含报错时间的完整ocp-server.log

[阿政]

版本号:4.3.6-20250815135607,没有找到日志文件ocp-server.log,

[旭辉]

服务器搜下

find / -name "ocp-server.log"

OBServer状态是正常的吗？是用的2881端口吗？

[旭辉]

另外ocp server机器和observer机器时间同步吗？

[阿政]

都正常,时间也是同步的Unhandled exception, type=NullPointerException就是这个提示

[旭辉]

看日志你ocp server服务器时间比标准时间快啊？

包含报错时间段的 完整mgragent.log也压缩发下

[OB_持续学习]

服务器之间有防火墙吗？

[cwa]

通过obclient黑屏从ocp机器能连上集群每台机器2881端口不
