I have Installed single node environment later I added a compute node. I have launch few instances on both controller node and compute node. After the few days I try to into console of instance on compute node, cannot leting me in th console but instances on controll node are working perfectly fine.

cat /car/log/nova/nova.compute.log | grep error

I have check the logs on compute node.ca5a-4fc0-9cbd-bc1a3bae337e] An error occurred while refreshing the network cache.
