I've got a k8s (on-premise) cluster with 1 master and 3 workers, all ubuntu, latest LTS version.

2 workers are running fine, but pods getting scheduled to one stay in the ContainerCreating state with the error.

Failed to create pod sandbox: rpc error: code = Unknown desc = failed to set up sandbox container "1234" network for pod "clean-updater-hxknv": networkPlugin cni failed to set up pod "clean-updater-hxknv_default" network: failed to set bridge addr: "cni0" already has an IP address different from

cni0 has an ip of:

cni0: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state UP group default qlen 1000 inet brd scope global cni0

I've tried kubeadm reset and join again on the node but it didnt help. How to fix this error?
