[Starlingx-discuss] openstack Failed to establish a new connection

[北邮_通信工程_刘启航]

Hi，



when I exploit openstack to build a network simulation, I encountered a problem like this.




$ openstack server list

unable to establish connection to http://nova-api-proxy.openstack.svc.cluster.local:8774/v2.1/a9e3d71fc89147e7aadd28179c03df6c/servers/detail: HTTPConnectionPool(host='nova-api-proxy.openstack.svc.cluster.local', port=8774): Max retries exceeded with url: /v2.1/a9e3d71fc89147e7aadd28179c03df6c/servers/detail (Caused by NewConnection Error('urllib3.connection. HTTPConnection object at 0x7faeab41b510>: Failed to establish a new connection: [Errno -2] Name or service not known',))




After waiting for a period of time, execute "openstack server list" again, and this error will not appear. The irregular appearance of this error bothers me.




Kind regards,
Qihang Liu
