Error:

The following timeout error is reported when connecting to Nacos:

[ce-c66db32658aa] c.a.n.client.config.impl.ClientWorker : longPolling error :java.net.ConnectException: no available server, currentServerAddr : http://my-nacos:8848

Resolve:

The version the project depends on does not match the version of Nacos Server;

My Nacos Server is 2.0.2, nacos-discovery and nacos-config are 2021.1, which contains nacos-client 1.4.1;

Exclude nacos-client from the nacos-config package and introduce nacos-client 2.0.3 version separately:

org.springframework.cloudspring-cloud-starter-loadbalancercom.alibaba.cloudspring-cloud-starter-alibaba-nacos-configcom.alibaba.nacosnacos-clientcom.alibaba.nacosnacos-client2.0.3
