RKE cluster stuck

Hi Good Evening,

I am trying to create the k8s cluster with the Rancher; the Rancher is deployed from the single docker container, and the version is v2.7.10. The underlying infra is vpshere, and we are trying to deploy k8s. We are encountering the issue.

2024/07/10 15:29:45 [ERROR] error syncing ‘all’: handler user-controllers-controller: userControllersController: failed to set peers for key all: failed to start user controllers for cluster c-m-rr6v8m4f: ClusterUnavailable 503: cluster not found, failed to start user controllers for cluster c-m-zkkbcvst: ClusterUnavailable 503: cluster not found, requeuing

The node is deployed on the sphere but shows an error like the above. Also, the rancher is deploying with our certificate.

Please advise for these errors.
