K3s upgarde system-upgrade-controller pod in pending state

Hi All,

I am getting issue when trying to upgrade the K3s cluster using automtic upgrade option. The reason I am doing upgrade is because of expired ssl certificate getting (error: You must be logged in to the server (Unauthorized)) error. To fix it temporarily, i have set the date on server in past for the last year. When I am trying to do the upgrade after following the instruction given here on rancher website (Automated Upgrades | K3s) the system-upgrade-controller pod is showing in pending state so please advise what could be the reason behind its pending state and how to fix it??

kubectl get pods -n sys-upgrade
system-upgrade-controller-7cfb4c4995-gzrst 0/1 Pending 0
