New cluster fails provisioning

Hello, I’m quite new to Rancher and wanted to try it out on a small cluster with 3 machines. So, I executed the Docker command on the “master” VM, then logged in to the web interface and tried to create a cluster with only that one node for the beginning. The web interface then shows “This cluster is currently Provisioning” and here it hnags forever. I took a look at the logs of the docker, these are the last few lines:
