 问题:业务服务启动报如下错误,

java.lang.IllegalStateException: failed to req API:/nacos/v1/ns/instance after all servers([172.17.38.223:8848]) tried:
	failed to req API:172.17.38.223:8848/nacos/v1/ns/instance. code:500 msg: java.net.SocketTimeoutException: Read timed out

在linux中启动命令为:

启动显示nacos以集群方式启动,能正常启动,但是业务服务连接超时

解决:

sh startup.sh -m standalone 以单机模式启动,问题解决
