In the k8s-node dashboard you can select per node metrics, I find in the query inspector all . are being rewritten to _ so the hostnames do not exist in prometheus and so... it returns nothing.

questions; how is this controlled and why is the char changing?

Having the exact same issue. Rewriting the underscore to dot in the URL does work. This will happen whit any query made with FQDN. Thanks in advance for the support.
