Traefik v2 and .net core signalr docker

does anyone have configured traefik v2 with loadbalanced .net core services with signalr hubs ?
it works fine if i have only one instance of my service active but fail if i have 2 or more instances of my service behind traefik.

This is very particular requirements, you'll be very lucky if someone here did exactly that.

In the meantime, if you can provide a reproducible set of steps to see your problem, I or someone else would probably be able to help.

thanks for your response.
I found the solution.
just need add this lines to docker
it works fine now
