This is the server configuration

My client configuration is like this

 

Solution:

Replace my client address with localhost address and it will run successfully

Here are some methods on the network
first, change the configuration of the. YML file or. Properties file:

#The lowercase letters after underline + underline are equivalent to the letters after uppercase underline without underline (hump principle)

eureka.client.registerWithEureka=false   #whether to register itself to Eureka-Server, default true registerWithEureka is equivalent to register_with_eureka
eureka.client.fetchRegistry=false #whether to pull service information, default is not true fetchRegistry is equivalent to fetch-registry

2、 Unregister dependencies and empty downloaded Eureka dependency packages:

<dependency>
   <groupId>org.springframework.cloud</groupId>
   <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
   <version>2.1.1.RELEASE</version>
</dependency>
