K3s ,rancher cluster import

Hello, I’m new to the whole cluster scene and thought it would be a fun project to create a k3s cluster with Raspberry Pis. I followed a YouTube tutorial by NetworkChuck for this. My node is up, but I’m having trouble importing it into Rancher. I’m using the curl --insecure command provided by Rancher. However, I keep getting the error “no objects passed to apply.” In most tutorials I’ve seen, this occurs, but after repeating the command, everything imports into Rancher. However, this isn’t the case for me. Does anyone know why this is happening? Best Regards
