Problem with upgrade to k8s 1.22

Dear Sir,

we had a cluster on linode cloud provider, recently they upgraded to the 1.22 and turn off the 1.21, we had a managed cluster with them.

know as they upgraded our cluster and website goes offline.

I appreciate any feed back on the upgrade to the 1.22, (we prefer rancher to provision our cluster but also faced some difficulty with it).

**with rancher we provisioned an unmanaged cluster work fine but we faced some issues with the configuration of the nginx ingress to the cloud load balancer, attached the sceenshot of the nginx controller and the load balancer, as the status shows pending continuously.

your replay is highly appreciated,
