Bug Description

我在部署jenkins的时候发现的问题，我本地有很多节点，取node001节点来讲，我的域名会设置成node-jenkins-001.xxx.top，但是这个域名在穿透的时候报错，无法访问，我检查了很多遍，配置其他的域名都没有问题，就这个域名报错了，然后我猜想可能是长度的原因，我把域名的s给去掉了，现在域名是node-jenkin-001.xxx.top，重新部署后可以使用了！！然后我把域名替换成node-jenkina-001.xxx.top，又不能使用了！！！，所以目前我发现，子域名的长度不能超过15位，长度17、18之后的我没有在测试，仅仅16位的就折磨我半天了。
