I am having problem installing fleet through Rancher v2.10.1 on a docker container on linux. Looks like it can't find the image for fleet. I have setup a system-default-registry for docker but Rancher seems to be pulling from docker.io . Any help appreciated. Here's. the error in the k3s.log

"Failed to create sandbox for pod" err="rpc error: code = DeadlineExceeded desc = failed to get sandbox image \"rancher/mirrored-pause:3.6\": failed to pull image \"rancher/mirrored-pause:3.6\": failed to pull and unpack image \"<http://docker.io/rancher/mirrored-pause:3.6\|docker.io/rancher/mirrored-pause:3.6\>": failed to resolve reference \"<http://docker.io/rancher/mirrored-pause:3.6\|docker.io/rancher/mirrored-pause:3.6\>": failed to do request: Head \"<https://registry-1.docker.io/v2/rancher/mirrored-pause/manifests/3.6>\": dial tcp 44.208.254.194:443: i/o timeout" pod="cattle-system/helm-operation-lk76l"
