403 Forbidden with jupyter but not voila directly (on remote server)

[artemisart]

Hello, I'm running voila on a remote server (aws ec2). When I use voila --no-browser it logs [Voila] Voila is running at: http://localhost:8866/ but I have not problem accessing it with serverip:8866 (it's not restricted to localhost apparently). However when I use it from jupyter serverip:8888/voila I get a 403 with these logs from jupyter (same with the 'Render with Voila' button inside jupyter lab interface):

[W 09:05:18.845 LabApp] Blocking request with non-local 'Host' serverip (serverip:8888). If the server should be accessible at that name, set ServerApp.allow_remote_access to disable the check.
[W 09:05:18.847 LabApp] 403 GET /voila (195.154.101.134) 2.29ms referer=None

I did change ~/.jupyter/jupyter_notebook_config.py to have

c.NotebookApp.ip = '*'
c.NotebookApp.allow_origin = '*'

and ~/.jupyter/jupyter_server_config.py:

c.ServerApp.allow_origin = '*'
c.ServerApp.allow_remote_access = True

But it still get the exact same errors and logs, any idea how to solve this?

Thanks!

@artemisart are you able to access the Jupyter Notebook interface?

Otherwise it might because the token is not passed as a parameter in the URL?

[artemisart]

@jtpio Yes I have no problem accessing the notebook and lab interface (we have setup a password and I'm already authenticated).

I am also having this issue. I can not get voila to render inside a JupyterHub dockerspawned single user notebook server. I get 403: Forbidden.

Hi, perhaps also related to this 403 error this error I get when visualizing pdfs in notebooks (working well) but not in voila_ https://stackoverflow.com/questions/62952128/ipywidgets-output-not-showing-pdf-when-using-voila

[maartenbreddels]

When I use voila --no-browser it logs [Voila] Voila is running at: http://localhost:8866/

You run voila standalone, and it runs at port 8866

serverip:8888/voila

Here you connect to jupyterlab, they are separate servers/processes. Connect to serverip:8866 instead.

I also think you need to add the VoilaApp.ip=0.0.0.0 argument to voila, otherwise you cannot access it.

Facing the same problem anybody has a solution to this

[engineerali2009]

Please use jupyter notebook --ip 127.0.0.1

[kasrakazemi]

Please use jupyter notebook --ip 127.0.0.1

this doesn't work

[jasonoberme]

Any fix here?

[jasonoberme]

Any fix here?

fix for which issue? #1074 ?

Sorry about the lack of clarity! My specific issue is remote access to voila gives a 403 forbidden but works on localhost.

I also tried --ip 127.0.0.1 but it similarly did not solve my problem.

[kasrakazemi]

try one of these:

1- run voila with config such as : voila --port=$PORT --no-browser --enable_nbextensions=True --VoilaConfiguration.file_whitelist="['.*\.(png|jpg|gif|svg|pdf|mp4|avi|ogg)']" something.ipynb 2- use latest voila and jupyter notebook(lab) versions

I second solution #2. Worked for me.
