When a customer setups a docker environment with Portainer installed. Next he disables the public IP and setups SLB.

He can connect to the containers but loses the Portainer connection and gets Error 502 Application Down. He has access when uses https://env-xxxxxxx.j.scaleforce.net:xxxxx but not with nodexxxxx-env-xxxxxxx.j.scaleforce.net:xxxxx because nodexxxxx pass the traffic from the shared load balancers, and this specific port is not distributed from them.
