Dask gateway server not starting up in binder

[jbusecke]

I just tried to run the sea surface height example in the physical oceanography gallery.

In the cell where the dask gateway cluster is requested:

from dask.distributed import Client
from dask_gateway import GatewayCluster
cluster = GatewayCluster()
cluster.adapt(minimum=1, maximum=10)
cluster

I am getting the following error:

I am able to run the full example when I clone it to the pangeo cloud on google, so I assume this is a problem with the binder environment? But I am generally not that familiar with these mechanisms yet. I would like to use this for an interactive demo tomorrow, so any pointers is greatly appreciated.
