出问题CAT的服务端:[192.168.1.110]
- 我百度和谷歌了几个小时，查看了几十上百篇博客，配置了各种参数，重启了无数次，改了无数次配置文件，还是显示 出问题CAT的服务端:[192.168.1.110]。一个链路追踪的软件，搞得比MySQL还要复杂，我现在都想放弃了，抗不住了。

- 脑阔疼，又冒出了一个问题，访问URL时，http的code=500，为啥会有各种问题
- 我平常开发的项目，如果出现这种问题，属于生产线上严重的bug，是不可以被接受的，整个项目团队都受影响

知道这个问题怎么解决吗？
建议看下这里为什么返回 null，可以加一些埋点 日志看看。
- 终于解决了，我给 JAVA_OPTS 配置了 -Dhost.ip=192.168.1.110 就可以了，不容易 牛🐂
我也是报500，但是我加了后还是报500
