Failed to create pod sandbox after installing Multus

[xutzin]

I followed the quick-start guide to install multus

cat ./deployments/multus-daemonset-thick.yml | kubectl apply -f -

After the installation, all pod creation failed even without network annotation

Kubeadm 1.29.1+ Kube-VIP + Flannel 0.24.2 (vxlan)

Any advice would be appreciated

It turns out to be network setting issue
