Sorry for the delayed response.
It must be that the new pod acquires a new IP. The solution for now will be to use --clean-cluster-config flag. This way the cluster config for the pod will be generated from scratch but you will have to re-initiate meet for that node.
Can you try this and let us know if that works?

Another solution would be for kubernetes to rely on dns hostname instead of IPs like proposed in #741
