Proxmox SSL Error Fixing

you can just delete the keys and certificates, and run "pvecm updatecerts -f" ?
 
if you delete the certificates and corresponding keys, everything will be regenerated! please post the exact version you are using, and which commands you run (including deletion of old existing files)
 
i upgraded my proxmox 3.x to 4.4 kernel is: pve-kernel-4.4.95-1-pve

After upgrade i removed certificates and run "pvecm updatecerts -f" and only generated pve-root-ca.pem.

Because of that i got this error: "kvm: -vnc unix:/var/run/qemu-server/NODENAME.vnc,x509,password: Failed to start VNC server: Our own certificate /etc/pve/local/pve-ssl.pem failed validation against /etc/pve/pve-root-ca.pem: The certificate hasn't got a known issuer"

After all these things I wrote my own method.

If there is a question, it is from me, but I wrote that someone like me would find the solution if they encountered this situation.
 
you need to remove the node certificates as well to regenerate them.
