remote connection to jupyterHub from code-server

[BouarfaMahi]

hey, i am currently building an AI Agent farm, code-server is installed on each of several microservers with ubuntu 22.04 server. I have also a GPU Server on which JupyterHub is installed. I am trying to connect remotely JupyterHub from code-server (docker) without success. i am using the following link /user//?token=. What i am missing or is it possible? thanks
