问题描述： 在进行Eureka高可用配置时，控制台一直出现“......”的错误，但是在浏览器中输入地址：peer1:8761 却是可正常运行。对此，我不懂为何控制台出现异常报错，但是浏览器中却可正确运行。
现在，我将我所遇到的现象进行如下描述。
创建的项目：microservice-discovery-eureka-ha ，其application.yml文件配置内容如下：
spring:
application:
name: EUREKA-HA
---
server:
port: 8761
spring:
# 指定profile=peer1
profiles: peer1
eureka:
instance:
# 指定当profile=peer1时，主机名是peer1
hostname: peer1
client:
service-url:
# 将自己注册到peer2、peer3这个Eureka上面去
defaultZone: http://peer2:8762/eureka/,http://peer3:8763/eureka/
---
server:
port: 8762
spring:
profiles: peer2
eureka:
instance:
hostname: peer2
client:
service-url:
defaultZone: http://peer1:8761/eureka/,http://peer3:8763/eureka/
---
server:
port: 8763
spring:
profiles: peer3
eureka:
instance:
hostname: peer3
client:
service-url:
defaultZone: http://peer1:8761/eureka/,http://peer2:8762/eureka/
对该项目创建3个启动项：peer1、peer2、peer3，在Run Configuration中的配置如下图peer1所示，peer2、peer3与peer1配置类似。
在控制台中报错信息如下：
