Share New Research 
I couldn't connect to the research environment since this early morning. Everytime when I try to launch my Jupyter notebook, it showed:
NameError Traceback (most recent call last)Cell In[1], line 2218 import tqdm20 # QuantBook Analysis Tool21 # For more information see [https://www.quantconnect.com/docs/research/overview]---> 22 qb = QuantBook()NameError: name 'QuantBook' is not defined
with Kernel: `base`, and showed prompt message **Failed to connect remote Jupyter server**. I tried to switch the kernel to another working kernel such as `Default-Python-Framework`, but it showed nothing when I clicked the kernel block and see error message below in the browser console window:
Desire value (Remote) Jupyter Kernel false
I've also checked the QuantConnect Status site and it seems nothing wrong with the server.
Is anyone having the same issue or any thing I should do to recover my remote Jupyter server?
Thank you.

Btw, I've also tried restarting the research node or even cleaning the browser cookies and caches, but nothing works as of now.
