K8s nodes without internet


Hello everyone,
I need help becouse all the nodes on the Managed K8S lost internet connectivity.

We have 1 node pool private. With the private network created snd gateway configured. Bu we dont know why that this evening all the nodes forgot internet connectivity. I try to create a new node pool but have the same issue.

Who is possible that the gateway/private networt lost internet. How I can solve with out remove the gateway and lost the IP?

Many thanks in advance
