It looks like the issue is in connecting to PyPI via SSL. Do you have a proxy on your network that is intercepting SSL certificates? Is there a way to capture the HTTPS request that is being made, such as by using Fiddler to intercept network traffic? I can't reproduce this, although I'm not using a proxy server. It would help if we knew what request, to which server, is causing this error. Thanks! |
Unfortunately I am not using any kind of special proxy, when you say which server are you saying which PyPi server? I'm not sure how to check this, the route that is failing on the JLab kernel is GET /lab/api/extensions?query&page=1&per_page=30&refresh=0&1704821307620 |
|
Can you access https://pypi.org/pypi from your computer without any issues with the certificate? You can alternatively try using a PyPI mirror (note that there are no officially endorsed mirrors, although some organizations run one) by running: |
Yes I am able to access it fine. Running jupyterlab with a mirrored pypi is also resulting in the same outcome. |
|
I get the same annoying issue in the backend and frontend under 4.0.10 on windows environment. |
|
I found pypa/pip#10939 on a web search; are you able to run |
Yes, I am able to |

I have 3 kinds of errors depending on how

Can you open a Python console for the environment where you start jupyterlab and check the openssl version with: |
|
|
|
Hmm, it seems like there might be an issue with tornado compatibility with OpenSSL 3.2.0. Someone just opened a bug report on the tests failing for it upstream yesterday: |
|
@krassowski To add up: I encountered similar ssl certificate error when I am dealing with fetch transcript from youtube: from pytube import YouTube
yt = YouTube('https://www.youtube.com/watch?v=QytLiiCJOcI&ab_channel=DoubleLineCapital')
video_info = {
"title": yt.title,
"description": yt.description,
"view_count": yt.views,
"thumbnail_url": yt.thumbnail_url,
"publish_date": yt.publish_date.isoformat() if yt.publish_date else "Unknown",
"length": yt.length,
"author": yt.author
}
print(video_info)It failed with But when I added these 2 lines before the previous code, this error will not happen: import ssl
ssl._create_default_https_context = ssl._create_stdlib_contextIs there a possibility of such SSL context issue happening here in jupyterlab on windows system? |
|
Not sure. Could you possibly check if applying the patch from tornadoweb/tornado#3357 solves it for you? |
|
@firezym @caleb-at-pieces Have you tried using the patch that @krassowski mentioned above? Thanks! |
|
@JasonWeill which version of jupyterlab should I test? |
|
@firezym This is used for Lab 4.0.x and Lab 4.1, which is currently in beta. The patch affects the server code that works with both of these Lab versions. |

Description
JupyterLab is saying that there is an uncaught error while trying to fetch the list of extensions, this also makes installing extensions from the extension manager impossible as the search feature does not work.
the error output in the jupyter lab shell
