I want to connect Google Colab to my local jupyter runtime. I installed the below extension as suggested by colab.
pip install --upgrade jupyter_http_over_ws>=0.0.7 && jupyter serverextension enable --py jupyter_http_over_ws
Then I run the command and started a jupyter notebook. After that I try to connect google colab to the local runtime with the prompted URL. But then I got the follow issue. Please help me to solve this.

I have been struggling with this problem the last few days. I am running Manjaro Linux on my laptop and I have recently installed Jupyter Notebook and Jupyterlab using pip.
However, when I try to run it, I get the following output:
[I 2021-05-20 16:21:19.980 LabApp] JupyterLab extension loaded from /usr/lib/python3.9/site-packages/jupyterlab

followed by a tab opening on my browser saying that it is unable to connect to the localhost.
I have tried different using browsers, and some of the answers given in other posts (downgrading tornado, for example) do not seem to work since now you're required to have the latest version of tornado.
Can anyone please help me?
Thanks,
E.
I didn't run jupyter notebook for a long time, Today when I try to launch to notebook , I can't run it and I encountered this:
[I 19:05:29.939 NotebookApp] 0 active kernels
[I 19:05:29.939 NotebookApp] The Jupyter Notebook is running at:

Opening in existing browser session.
Then can not open in browser. I looked up other similar question but I didn't find to solution.
I've had docker to use the jupyter notebook with tensorflow.
(My OS is window 10 so I use the Powershell.)
I want the jupyter to open the web browser automatically. When I try to initialize jupyter notebook.
For instance, I enter the command to start anaconda image (including tensorflow).
> docker run -it -v ~/tensorwork:/notebooks -p 8888:8888 anaconda3
And activate tensorflow
(base) root#e088a0e0e58e:/# conda activate tensorflow
After entering tensorflow kernel mode, I execute jupyter notebook.
(tensorflow) root#e088a0e0e58e:/# jupyter notebook --ip '*' --allow-root

Execution of the jupyter notebook works well.
However, I manually enter the URL my browser to enter the notebook.
I guess this problem came from docker's feature. The container's file path needs to be connected to the local host so that jupyter can find the default web browser(chrome) that I use.
But how can I make it possible? I've already tried the editing config of jupyter notebook.
Before I execute jupyter notebook, I enter the command as following:
jupyter notebook --generate-config
vim ~/.jupyter/jupyter_notebook_config.py # or use your favorite editor
c.NotebookApp.browser = u'chrome'
(refer ; https://groups.google.com/a/continuum.io/forum/#!topic/anaconda/oXjbKNMyP30)
But the jupyter still said it cannot find any web browser. Help me please :)
1) I tried to open Jupyter Notebook in Anaconda prompt.
Ananconda Prompt:

2) My default browser is Google chrome and every time when I try to open the Jupyter notebook, the following is the result.
Result in the Browser(Google Chrome):
ERROR: Gateway Timeout

3) I interrupted the process using 'Ctrl+C'.. it displays as follows.
[I 19:43:23.364 NotebookApp] Interrupted...
[I 19:43:23.365 NotebookApp] Shutting down kernels
I have googled about this issue, but had very little help which is of no use.
It seems like you're trying to open Jupyter Notebook in port 8888 as stated by the error message While trying to retrieve the URL http://localhost:8888/tree?token=4f3786890eceb91493af9bd6f4b07ae1ac6888c6172bbfca
But, when running Jupyter Notebook, there was an error message stating something else is running in port 8888 and it started the server in the next available port, which is 8889: [I 19:26:39.239 NotebookApp] The Jupyter Notebook is running at: http://localhos t:8889/?token=86664b50ba28f3bd3431554bc84d60d8bf4f3bf4209a4ecf
I'm not sure how to identify what is running on 8888, but you should definitely access your Jupyter Notebook on localhost:8889 .
I am running Ubuntu 64-bit and using IPython from the Anaconda distribution. When I type "ipython notebook" in terminal, everything starts up as it should. But when I create a new notebook, or open an existing one, the kernel dies, tries to restart, and fails.
Here is the info from terminal for the entire session, with the errors:

When I use IPython (without the html) from the terminal, everything works fine. I have reinstalled IPython, but that did not change anything. Any help is very much appreciated. Thanks!
Try to run
import socket
print( '127.0.0.1 ' + socket.gethostname() + '.local' )
And add output to /etc/hosts
It will help if problem in socket.gethostbyname_ex
Related question gethostbyname_ex(hostname) extremely slow
Also this may help
conda remove pyzmq
conda install pyzmq=14.6.0
