Hi all, Recently I have upgraded rancher version from v2.6.3 to v2.7.9 with this command

helm upgrade rancher rancher/rancher \
 --namespace cattle-system \
 --set global.cattle.psp.enabled=false \
 --set hostname=rancher.my.org

all rancher pods are up and running but rancher ui getting "404 not found error"
