Can not associate the floating ip to instance
When I associate a floating ip to the instance, create success, but can not attach it to the instance.
The error information:
Error: External network 8603929d-6d3b-44dd-af59-d9a4f77d4048 is not reachable from subnet 4c76341d-c7b4-49a4-add9-465eb1696344. Therefore, cannot associate Port 14b82c66-209a-4c64-9791-49042a3667e3 with a Floating IP. Neutron server returns request_ids: ['req-ae0d016c-97a9-408d-9a40-2bf741463034']
Error: Unable to associate IP address 45.117.40.62.
And in the Project->COMPUTE->Instance all are down.
