Cluster Registration Woes

SUSE Rancher Prime
1

I’m running a single node with Rancher v2.7 and kube 1.25.9+k3s1. I’m trying to register a k3s cluster on two RHEL nodes. That cluster is running the same version of kube. When I do the registration I initially get an crash look about an untrusted cert. So I use the option to run the yaml input to the cluster while bypassing the ssl, but I get the same issue with the start up, so unsure how to proceed…
