Kernel not working using an on premise Kubernetes Cluster

Good morning,

As far as I can see, I discovered that the connection to the kernel is done through a WebSocket, which is different than http or https (returning HTTP 504). I’m using IngressController to expose proxy-public (http and https), but maybe I need to expose another think, or it will only work if using LoadBalancer Service.

Is it possible to configure the connection port with the kernel? Which additional things do I need to configure in Kubernetes?

Do you know what can I do?

Thanks,
