Container stuck at creating in kubernetes

4/9/2020

Am trying to create a deployment for exhibitor, when i execute the kubectl apply command container stuck at creating status. When i describe it, am getting the below error.

Note:- For other pod am not getting any issue and am using flannel network.

Failed to create pod sandbox: rpc error: code = Unknown desc = [failed to set up sandbox container "0d459281ccc36f" network for pod "exhibitor-6fdcbdf9c-d7t6v": networkPlugin cni failed to set up pod "exhibitor-6fdcbdf9c-d7t6v_default" network: error getting ClusterInformation: Get https://[10.96.0.1]:443/apis/crd.projectcalico.org/v1/clusterinformations/default: x509: certificate signed by unknown authority (possibly because of "crypto/rsa: verification error" while trying to verify candidate authority certificate "kubernetes"), failed to clean up sandbox container "0d422ffb519a9a9be4dfbd9c6b235505f5a0e8181ccc36f" network for pod "exhibitor-6fdcb9c-dt6v": networkPlugin cni failed to teardown pod "exhibitor-6fdcbc-t6v_default" network: error getting ClusterInformation: Get https://[10.96.0.1]:443/apis/crd.projectcalico.org/v1/clusterinformations/default: x509: certificate signed by unknown authority (possibly because of "crypto/rsa: verification error" while trying to verify candidate authority certificate "kubernetes")]
