SpringCloud使用 Nacos做注册中心客户端启动报错 java.lang.IllegalArgumentException: no server available at com.a...

java.lang.IllegalArgumentException: no server available at com.alibaba.nacos.client.naming.net.NamingProxy.reqAPI的解决方案

SpringCloud 版本是 Hoxton.SR6

首先看看总依赖springcloud Alibaba 版本号是：

com.alibaba.cloudspring-cloud-alibaba-dependencies2.1.0.RELEASEpomimport

以上配置报错 no server available 没有可用的服务器

nacos registry, cloud-user-service register failed…NacosRegistration{nacosDiscoveryProperties=NacosDiscoveryProperties{serverAddr=’’, endpoint=’’, namespace=’’, watchDelay=30000, logName=’’, service=‘cloud-user-service’, weight=1.0, clusterName=‘DEFAULT’, namingLoadCacheAtStart=‘false’, metadata={preserved.register.source=SPRING_CLOUD}, registerEnabled=true, ip=‘192.168.109.1’, networkInterface=’’, port=8001, secure=false, accessKey=’’, secretKey=’’}},
