Hello everyone,

I have been stuck on this issue for a while now. I have been trying to use jupyter on my virtual desktop, but my notebook is not capable to connect to the kernel. I have been looking around, and I believe that it probably has to do with server configurations, etc. which are out of my control and under the administrators of the virtual desktop control.

Anyway, here’s the information I can share with you.

What happens when I launch `jupyter notebook --debug` :

```auto

I have the following kernel specifications. I have removed my python path to use instead the `ipykernel `package, as a thought this might help :

```auto
(temperature) C:\Users\jewell>jupyter kernelspec list
Available kernels:
  python3 C:\Users\jewell\Miniconda3\envs\temperature\lib\site-packages\ipykernel\resources

```

**EDIT**

I have a functioning environment when I clone the base environment from Anaconda. Jupyter then works. However, when I try to create a new environment and load only jupyter (and its dependencies), the same problem arises.

- Problematic environment Web console

- Functioning environment terminal output when launching jupyter (funnily calls jupyter lab --\> important?)

```auto
(temperature) C:\Users\jewell>jupyter notebook

[I 12:42:24.773 NotebookApp] Use Control-C to stop this server and shut down all kernels (twice to skip confirmation).
[C 12:42:25.007 NotebookApp]

    To access the notebook, open this file in a browser:
        file:///C:/Users/jewell/AppData/Roaming/jupyter/runtime/nbserver-9752-open.html
    Or copy and paste one of these URLs:
        http://localhost:8888/?token=37941e3942674c5d27c61f15cf2a796f173cc8d1e06a3643

```

Can you bring up your browser’s developer console and see if there are any warnings/errors when you try and run a notebook?

@manics I have added what you asked. Just in case, here is the list of packages I have in the cloned environment.

- Functioning environment package list (clone from Anaconda base environment). Because it is a clone, there are many packages that I don’t need ^^

One thing that stands out is you’ve got a very old version of `notebook`, `4.4.1`, in your `temperature` conda environment. Could you try upgrading it?

@manics Thank you very much! This was the solution indeed 🙂 I tried unsuccessfully `conda update notebook`, but then I tried `conda install notebook=6` which worked out. Again, thank you very much 🙂

It seems that after **eight months** this issue is still alive.

In my case, I created a new virtual environment but I did not want to install Jupyter notebook again via `conda install -c conda-forge notebook`, so when I opened the notebook did not work in this environment.

After reading this discussion I used `conda install notebook=6.1.4`, which was the version used in another virtual environment that I have, and it **worked!**.

However, I was wondering if every single virtual environment needs this installation.  
I found some discussions about this but nothing concrete, or it did not work for me in the same way that for others.

Anyways, thank you guys for starting this discussion.
