What happened:
I updated the os of a cluster and after rebooting a node I got the openstack-cinder-csi-nodeplugin on just one node with the following error:

The issue happened on just one worker node, all the other are ok.

What you expected to happen:
pod working fine

How to reproduce it:

• reboot a node

Anything else we need to know?:
The nodes are running Ubuntu 22.04 updated.

Environment:

• openstack-cloud-controller-manager(or other related binary) version: 2.30
• OpenStack version: Zed
• Others:

I found out that the IP was a special one from the cloud system (169.254.169.254) and it is dedicated to give metadata to VMs. So the issue is not of the cinder CSI plugin, but it is related to the OpenStack installation.
