Bug description
When I try to spawn a JupyterLab instance using the Slurm spawner, the job launches according to slurm, however, the jupyterhub window just stays in the "Your server is starting up" page.
Expected behaviour
Allow me to enter the JupyterLab session that is launched
Actual behaviour
Stuck in launch screen.
How to reproduce
Your personal set up
There is a firewall between the Hub and the Lab, but I've temporarily disabled it for testing purposes. It seems like JupyterLab can communicate with JupyterHub, because when I stop JupyterHub, JupyterLab starts spitting out connection refused messages - leading me to believe that it was communicating when it was up.
Maybe there is some batchspawner configuration I'm missing with the 1.0 update?
