failed to req API:/nacos/v1/ns/instance after all servers([localhost:8848]) tried: java.net.ConnectException: Connection refused: connect

This error message indicates that the client failed to connect to the Nacos server API endpoint on localhost:8848. The most likely cause is that the Nacos server is not running or is not accessible from the client machine.

To resolve this issue, ensure that the Nacos server is running and that the API endpoint is accessible from the client machine. You can also check the server logs for any errors or issues that may be preventing the client from connecting. Additionally, ensure that the client is configured to use the correct API endpoint and that any necessary authentication credentials are provided.

这是一个Java异常，意思是在尝试请求Nacos服务注册中心的实例时出现了错误。所有可用的服务器（这里只有一个本地服务器）都尝试过了，但是仍然无法连接。具体错误信息是连接被拒绝，可能是因为服务器没有启动或者端口被占用等原因导致的。
