Which version of Jupyterhub and Jupyterlab are you using?  
For the latest lab, the way to user RTC is to install the plugin `jupyter-collaboration`.  
Then with your config, `user1` should be able to share his server by clicking on the share link (upper right corner) with `user2` (logged in).

I recommend to first test your config with a docker before using any cloud provider. See, for example, [my recent post](https://discourse.jupyter.org/t/jupyterhub-4-0-x-with-jupyter-collaboration/20961).
