I've been using jupyter notebook in my root environment and a few other environment for several months. Upgraded to jupyter notebook 5 last week and it worked well until yesterday.
Yesterday - computer froze. After restarting, jupyter notebook gives an error (2x) when launched from root environment:
(some info replaced with # below)

I've tried copying and pasting the link provided above. It removed one of the error messages next time it was launched, then 2 error messages after trying to launch again.
Jupyter notebook works when launched from a different conda environment.
Any thoughts on how to get this working in my root environment again?

I'm having a weird problem with Jupyter notebook running inside a WSL2 instance. Every time I start a new notebook, my first connection to localhost:8888 (or localhost:XXXX for any other port number) takes a LONG time to connect, like 5-10 minutes. Once one connection to that port has been made, however, all subsequent connections happen at a normal speed. As far as I can tell the delay is not specifically happening within the Jupyter server, as the server output doesn't show any GET requests during the waiting period:
> jupyter notebook .
[I 08:29:21.282 NotebookApp] Authentication of /metrics is OFF, since other authentication is disabled.
[W 08:29:21.729 NotebookApp] All authentication is disabled. Anyone who can connect to this server will be able to run code.

5-10 MINUTES ELAPSE

[I 08:38:12.718 NotebookApp] 302 GET / (127.0.0.1) 2.110000ms
However, the issue does appear to be limited only to Jupyter: if I just listen on the port with nc -l 8888 and then point my browser to localhost:8888 the GET request shows up immediately.
I have tried random fixes to other problems that I found on SE, eg. this one, but to no avail. Any advice, or even a suggestion as to where to start looking, would be greatly appreciated! This is driving me bonkers, although I am getting a lot of chess in while I wait for my notebooks to load :D
Old answer
I found 2 ways to get around the "waiting time" on my system.
Hit Ctrl+C once after the console output hangs at Use Control-C to stop this server and shut down all kernels (twice to skip confirmation).
Set the DISPLAY environment variable to nothing: DISPLAY= jupyter notebook .. Apparently, the same trick works for pip.
UPDATE 1
After some debugging I figured out, that the --no-browser option does the trick as well:
jupyter notebook --no-browser .
jupyter-notebook by default opens localhost:8888 in the browser.
I assume WSL2 has problems opening the default browser, and therefore times out.
UPDATE 2
To confirm my guess, from UPDATE 1, I set up WSL to be able to open a browser window:
Installing firfox in WSL (ubuntu):
sudo apt install firefox
Setting up X11 forwarding on WSL2
Using this setup jupyter-notebook starts normally and localhost:8888 is opened in firefox.
I open Anaconda and then open Jupyter notebook (6.1.4).
http://localhost:8903/tree is opened
However, when I click New Python3 a blank page with below address opened. It keep spinning, look like trying to open the python3
http://localhost:8959/notebooks/Untitled21.ipynb?kernel_name=python3
Also a notice box "Application Launch error" appear with following text
Can anyone help, please?
Thanks

I have using jupyter notebook for past few months. I am facing this type of problem for the first time.
Exact Problem : When I run a cell on jupyter notebook it is running for long time, but not showing any output.
Solution that I have already tried based on some google searches:
1. Uninstalled anaconda and reinstalled it.
2. Updated conda
3. Updated ipykernel
4. Download and installed microsoft visual c++ 2015 redistribute update 3
5. Restarted kernel and tried again
6. Shutdown files in running tab
7. And so on.
Properties:
1. Windows 10 Pro
2. Python : Python 3.6.7
3. Jupyter :-
jupyter core : 4.6.3
jupyter-notebook : 6.1.1
qtconsole : 4.7.5
ipython : 7.16.1
ipykernel : 5.3.4

Advance thanks for sparing time on my question.
At one point I set my Jupyter home directory to ~/Dropbox Unfortunately, because of the way Dropbox changed their folder name that location is now a symbolic link on my machine that points to a hidden directory. This causes the following error in Jupyter
Refusing to serve hidden directory '/Users/alex/Dropbox', via 404 Error
That's fine ... I'd like to now change my Jupyter home directory, but the issue I'm having is that I can't figure out where it's currently set.
I've checked my ~/.jupyter/jupyter_notebook_config.py but that seems to be unmodified from the default.
The output of $jupyter --paths is :
config:
/Users/alex/.jupyter

/usr/local/Cellar/python#2/2.7.14_3/Frameworks/Python.framework/Versions/2.7/etc/jupyter
/usr/local/etc/jupyter
/etc/jupyter
Setting c.NotebookApp.notebook_dir = '/Users/alex/' in /Users/alex/.jupyter/jupyter_notebook_config.py seems to have no effect.

Where could the Jupyter home directory be set from?
It is the intended behavior of jupyter notebook to throw a 404 when starting it from a hidden folder.
Generally, jupyter notebook will start in the folder where you invoke the jupyter notebook command. So cd into the directory where you want it to run from, and issue jupyter notebook there.
If that doesn't work, you can try forcing the directory with a command line argument like jupyter notebook --notebook-dir=NEWDIR.
Otherwise, there is a global config and a local (per user) one you refer above. If the local is the default, then you probably changed the global config earlier. If you change your local config in ~/.jupyter/jupyter_notebook_config.py to the new value that should override the global config.
To clean up the global config, look for it in /etc/jupyter or /usr/local/etc/jupyter/ on Unix or %PROGRAMDATA%\jupyter\ in Windows.
You can list the current config paths used with the command jupyter --paths. More info in the manual.

Can someone helps figure out what there is 0 active kernels? I have add the following in my ipython_nootbook_config.py file
#kernel config
c.IPkernelApp.pylab='inline' # if you want plotting support always
#Notebook config
c.NotebookApp.certfile=u'/home/ec2-user/anaconda/certificates/mycert.pem'
c.NotebookApp.ip='*'
c.NotebookApp.open_browser=False
c.NotebookApp.password=u'sha1:0d4773e470e5:2a91dcf5a15875f15c4ad18f9d3
4c95be563f804'
#It is a good idea to put it on a known, fixed port
c.NotebookApp.port=8888
#-------------------------
The number of running kernel has nothing to do with that.
