Added new node to my kubernetes cluster, why is it still in provisioning state after an hour?

Hi community, I followed the tutorial here, and tried to add a new (second) node to my existing node pool: https://www.digitalocean.com/docs/kubernetes/quickstart/#edit-nodes-and-node-pools-for-an-existing-cluster

After an hour, it is still “provisioning”. I cannot access the kubernetes dashboard, neither can I deploy anything with kubectl (I get the error “Unable to connect to the server: dial tcp … i/o timeout”

I also get a “Sorry, something went wrong” message in the UI.

Does anybody have an idea? Thanks!
