Rancher provisioning error

Hi everyone,
I’ve recently installed Rancher manager on my bare metal RKE. After importing Mirantis Kubernetes, I get the following provisioning error shown on the Rancher dashboard. All pods in cattle-system and cert-manager are running fine. I’ve been searching for a solution for two weeks, without success. Please help. Any advise or insight into this issue is appreciated.

Here is some information about my systems:

  1. Rancher Manager version - v2.6.8
  2. RKE (hosting rancher manager) - v1.20.15, single node
  3. Imported cluster - v1.21.8-mirantis-1, cattle-system pods running
