Rancher with docker single node

Hi I try setup one rancher single node using docker but when i start the worker using the : sudo docker run -d --name rancher-agent --privileged --restart=unless-stopped --net=host -v /etc/kubernetes:/etc/kubernetes -v /var/run:/var/run rancher/rancher-agent:v2.5.12 --server --token llt46sqbfxfxqbm7qpfjd6nj8sgvtpjqd5ndjx6678d4bnld6dnrk4 --ca-checksum e0c5deaabae5fb132353d141cb25476c52c44c5960a8a5551ba88ff2bf4e2fe7 --etcd --controlplane --worker i have error into the container: tls: failed to verify client's certificate: x509: certificate signed by unknown authority. The rancher server and rancher agent still run into do docker on some host. I try using one Ubuntu 20.04 host and One mac OS X Catalina.
