I'm not sure what you are trying to achieve, but you will get better response 
of Jupyter in the browser if the browser is running on your client, rather than 
your server. I suggest you use ssh port forwarding. You will need something 
like this on your client:

$ ssh -NL localhost:8080:localhost:8080 username@serverA

You will get asked for the password and can then point your client's browser at 
localhost:8080 to access the Jupyter server (this assumes 8080 is the local 
port it is running on).

How to Use SSH Tunneling to Access Restricted Servers and Browse Securely - 
How-To Geek<https://www.howtogeek.com/168145/how-to-use-ssh-tunneling/>
An SSH client connects to a Secure Shell server, which allows you to run 
terminal commands as if you were sitting in front of another computer.But an 
SSH client also allows you to “tunnel” a port between your local system and a 
remote SSH server. There are three different types of SSH tunneling, and 
they’re all used for different purposes.

Subject: [jupyter] Multiple X11 forwardings on ubuntu and jupyter-notebook

Dear All,

We are using jupyter-notebook for educational purpose. We are facing the below 
issue. Please disregard this post if it is irrelevant to the discussion group.


I have installed jupyter-notebook on an ubuntu 18.04; let us call it Server A. 
I successfully establish SSH to server A initiated by my client ( Client B). I 
am able to visually forward X11 running of Firefox to Client B using the below 
command.

On Client B:
SSH -X@Server A ip Address
user1# sudo jupyter-notebook --allow-root
user1# firefox &

Now, Inside the jupyter-notebook in firefox tab, I am able to execute a 
GUI-based application - I am able to run Linux shell command inside the firefox 
tab(jupyter-notebook session).

!xclock

The problem is that the xclock is executed on the Server A successfully, but it 
is not forwarded to a new X11 window on the Client B. Is it possible to forward 
xclock(GUI Application), which is initiated by the jupyter-notebook session 
(firefox tab) to client B, while the firefox is also initiated by SSH 
connection from Client B?

Sincerely,
Mohammad
