Question

我正在尝试使用DNS配置来设置Eureka服务器，但无法进行设置。下面是我的配置。

eureka: 
  datacenter: cloud  
  instance:
    nonSecurePort: ${server.port}   
  client:     
    fetchRegistry: true
    eurekaServerURLContext: eureka
    region: us-east-1
    eurekaServerPort: 8761
    useDnsForFetchingServiceUrls: true
    eurekaServerDNSName: dev.domain.com
    registerWithEureka: true
  server:
    renewalPercentThreshold: 0.49    
    enableSelfPreservation: false

这些是我配置的TXT记录

TXT记录

txt.us-east-1.dev.domain.com -> txt.us-east-1b.dev.domain.com; txt.us-east-1d.dev.domain.com

txt.us-east-1b.dev.domain.com -> eureka-us-east-1b.dev.domain.com 
txt.us-east-1d.dev.domain.com -> eureka-us-east-1d.dev.domain.com

CNAME：

eureka-us-east-1b.dev.domain.com -> ec2-xx-xxx-xxx-xxx.compute.dev.domain.com

A记录：

ec2-xx-xxx-xxx-xxx.compute.dev.domain.com -> xx.xxx.xxx.xx

启动应用程序时，eureka UI正常显示；但是，我在日志中看到以下内容。

我想知道为什么Eureka此处的EIP配置错误？另外，在UI页面上，“可用副本”行为空，实例显示在“不可用副本”中。

我在这里可能会缺少什么？

即使使用DNS配置了EIP，为什么Eureka DNS配置也会引发异常？
