That's not the issue, I am able to access your repository just fine. I'm just not using minikube, I'm using a real 3-node k3s cluster on my local network, so I only followed from step 14 in your guide since I think the minikube, metallb and nginx steps are not relevant in my setup.
I've written up a separate forum post describing all my steps in detail here, would greatly appreciate any more help!
