Hello Rancher Team, I’m new to rancher and trying to setup v2.6 over single node with docker. I am having following errors. Appreciate If anyone can help. Here is how my setup is. single node docker image running behind nginx as reverse proxy (it is docker-compose.yml having both containers). That single node is behind AWS classic load balancer. following are the errors being logged by rancher node (docker-compose logs -f).

I have another AWS EKS cluster. I am trying to import in above rancher instance. It is showing

waiting

status.

don’t put it behind all that stuff. rancher wants to use websockets for both browser and downstream cluster connections and one or both of those things are breaking it.

@creamy-pencil-82913 Thanks for your response. You are right, I observed websocket from browser and downstream. I’ll give it a try over eks.
