[Solved] failed to req API:/nacos/v1/ns/instance after all servers

Scenario: CentOS virtual machine SpringCloud-Nacos Dubbo integration error reporting
failed to req API:/nacos/v1/ns/instance after all servers([192.168.56.101:8848, 192.168.56.102:8848, 192.168.56.103:8848]) tried: failed to req API:192.168.56.102:8848/nacos/v1/ns/instance. code:400 msg: <html><body><h1>Whitelabel Error Page</h1><p>This application has no explicit mapping for /error, so you are seeing this as a fallback.</p><div id=’created’>Fri May 21 01:29:11 CST 2021</div><div>There was an unexpected error (type=Bad Request, status=400).</div><div>receive invalid redirect request from peer 192.168.56.101</div></body></html>
Cause.
When the nacos service is started, the virtual machine’s enp0s3 NIC is used with an ip of 10.0.2.x

So the solution here is to open the configuration item in /nacos/conf/application.properties and specify the ip on it
