Expected behaviour

Connect to remote jupyter server and select kernel from list

Actual behaviour

Cannot select kernel and cannot run cell with remote jupyter server.

Steps to reproduce:

Open a jupyter notebook
Select another kernel
Select Existing JupyterHub Server...
Provide JupyterHub Server URL, enter Username and Password
Select a running server. In my case it is "yt_kh"

I should be able to see a list of kernels available in "yt_kh", but I dont.
I am able to use "yt_kh" using JupyterHub on my web browser. I can select the kernel and run my notebooks with no issues.
