VS Code connecting to jupyterlab server not selecting kernel

We have recently moved to a JupyterLab Server from another IDE. We are trying to get VS Code hooked up so that we can code in it rather. After much struggle, we got VS Code to connect to our remote JupyterLab server. On the status bar in the bottom, it shows
However, as soon as we connect to the JupyerLab server, all the 'run' buttons on screen disappears.
We are getting no support from our IT and have to figure it out ourselves.
A colleague suspects that it (VS Code) is not picking up the python kernel from the server. How do we go about selecting it? or pointing to it?
An additional question, how do we see and browse the folders on the JupyterLab server in VS Code?
Appreciate any assistance

I think the problem is that you didn't really connect to the remote server.
Install Remote-SSH extension. Then you can see the button on the bottom left. Click and you can connect to your service and view your folder.
You can read document about Remote-SSH for more details/
Connect to a remote Jupyter server.
According to the document about jupyter, you have to do the following steps:
Open the Kernel Picker button on the top right-hand side of the notebook (or run the Notebook: Select Notebook Kernel command from the Command Palette).
Select the Existing Jupyter Server option to connect to an existing Jupyter server.
To connect to an existing server for the first time, select Enter the URL of the running Jupyter server.
When prompted to Enter the URL of the running Jupyter server, provide the server's URI (hostname) with the authentication token included with a ?token= URL parameter. (If you start the server in the VS Code terminal with an authentication token enabled, the URL with the token typically appears in the terminal output from where you can copy it.) Alternatively, you can specify a username and password after providing the URI.

Invalid token when trying to login into Jupyter notebook with Docker jupyter/tensorflow-notebook

I pulled a (seemingly popular, supported by Jupyter) jupyter-tensorflow Docker image using
docker pull jupyter/tensorflow-notebook
and started it successfully with
docker run -p 8888:8888 jupyter/tensorflow-notebook
However, upon navigating to http://127.0.0.1:8888/?token=177a...., I am prompted for a password or token (despite the token already being present in the URL).
I know of no password to use, and the token 177a... does not work.
Any suggestions?

The answer turned out to be quite easy: there was an other Jupyter notebook server I wasn't aware of running. Closing it did the trick.

Google Colab wont connect to local runtime after update

I recently updated jupter_over_ws to version 0.0.7 and now Google Colab refuses to connect my local runtime.
I have tried multiple iterations of launching the localhost in chrome, running with --no-browser etc and keep receiving a 'Forbidden' 403.
The last iteration I got to in an attempt to connect to the notebook was:
jupyter notebook --NotebookApp.allow_origin='https://colab.research.google.com' --NotebookApp.port_retries=0 --notebook-dir="" --no-browser --allow-root --NotebookApp.token='' --NotebookApp.disable_check_xsrf=True --port=8888
Any help much appreciated

Colab recently updated it's local runtime connection instructions.
In particular, you'll need to provide the URL printed in the console when starting the local runtime.
Clicking the "More Details" button in the local connection dialog will provide additional instructions.

After update, you need first upgrade jupyter_http_over_ws:
pip install --upgrade jupyter_http_over_ws
And second, everytime you start the server with this code:
jupyter notebook --NotebookApp.allow_origin='https://colab.research.google.com' --port=8888 --NotebookApp.port_retries=0
It will show a new token in Anaconda's prompt, you need to copy.
When you click in Connect to local runtime in Colab, a box will ask for the token, then paste there.

I solved this by removing the password from the jupyter .config file, then copy and pasting the token url as you have outlined in the answers above, and as outlined in the official colab documentation:
https://research.google.com/colaboratory/local-runtimes.html

If you use Anaconda, you can follow the instructions:
Open cmd.exe as Administrator
Run pip install --upgrade jupyter_http_over_ws>=0.0.7 && jupyter serverextension enable --py jupyter_http_over_ws
Run jupyter notebook --NotebookApp.allow_origin='https://colab.research.google.com' --port=8892 --NotebookApp.port_retries=0
Copy the URL from the command prompt printed console ex: http://localhost:8892/?token=fecaca2501d00f89971ab8fb4a5add3ff682ade7e63f7265
Paste the URL including token in Google Colab connection settings as Backend URL

Jupyter Notebook does not open browser after changing the default browser

The default browser for my Jupyter Notebook was Internet Explorer and it was working fine with that. I have windows 10. I changed the default browser to Firefox by following steps in this website :
https://support.anaconda.com/hc/en-us/articles/360024044333-Change-default-browser-in-Jupyter-Notebook
However now the notebook does not start automatically in Firefox and it tells me to copy and paste:
Copy/paste this URL into your browser when you connect for the first
time,
Can anyone tell me how to open Jupyter Notebook automatically in Firefox since above were the steps recommended by anaconda website. By the way after copying and pasting the link in the Firefox I can open notebook fine. I just need to know how to ask notebook to open automatically in Firefox like it was working in Internet Explorer.

c.NotebookApp.browser = u'C:/Program Files (x86)/Google/Chrome/Application/chrome.exe %s'
make sure you remove the hash(#) before the c.Notebookapp, and your escape key

Jupyter notebook not opening from Centos 7

I have recently installed jupyter notebook on Centos 7. I have been trying to get it launched on my browser from past 2 days and have tried every answer on stack overflow. It stopped showing " No web browser found " when i type it on the command terminal. But when i copy and paste the link onto the google chrome browser it's showing, This site can't be reached.
How will i resolve this issue?

If you follow carefully the instructions on this post, you'll solve your problem.
I went through the same situation and followed these steps.
https://techknight.eu/2016/01/03/setup-jupyter-notebook-centosrhel-7/
The key is to :
Modify the configuration .py file with your desired values (specially the IP on wich the notebook will run).
Allow the port you're gonna use throug the CentOS firewall
In any case, if you break the configuration and you need a fresh start, you can always do:
jupyter notebook --generate-config
And the file will regenerate with default values.
Good Luck
