Hi there 👋 I was able to join an AWS node with a GCP node using K3s and Kilo and this made my day. Honestly. I never before worked so deep down the network layer (configuring WireGuard to establish a VPN) and I’m pretty proud of myself 😁 The current state is committed to the repository. Only the Azure node is making trouble. I read that

--node-external-ip

must be provided as argument to the primary K3s node, which I did (steps are documented here). Still the setup of K3s fails with this error:

[root@az-japaneast-node azureuser]$ curl -sfL <https://get.k3s.io> | K3S_URL=<https://10.0.0.1:6443> K3S_TOKEN=$K3S_TOKEN sh -

Does anyone maybe have an idea how to resolve that?
