Some certificate error?

Hi Everyone,

just install Harvester on two nodes and create a VM. Everithing looks fine, but wfter a few hours I got an error in case try do anithing with the VM.

Internal error occurred: failed calling webhook “”: failed to call webhook: Post “https://virt-api.harvester-system.svc:443/virtualmachineinstances-mutate?timeout=10s”: tls: failed to verify certificate: x509:

I did reboot of both nodes and the error is gone. Please, can you help me to understand what ia all about? I am totally new in Harvester and Kubernetes. So have no idea from what to start.
