Argo tunnel Kubernetes Sidecar causing 503's

I have setup Argo tunnel as a Sidecar in a Kubernetes cluster

I am trying to expose a Grafana instance. This worked on Friday.

The problem that I am getting is that it gets to Grafana however, when trying to load assets on the exact same host name I am getting a 503.

There are no errors in the tunnel container. I am not really sure where to go from here

I’m interested in seeing your configuration.
