I get some form of a connection error every time I launch Jupyterlab.
I think it's related to the fact that I'm behind a corporate proxy, and the PYPI manager component attempts a connection that gets blocked. I can see that from the attached screenshot where the Discover Extensions section returns an "Error searching for extensions: Error: Unhandled error". I can't install any extensions indeed.
I've already tried to set the proxy by adding a file called 00-startup.py under .ipython\profile_default\startup
import sys,os,os.path
os.environ["HTTP_PROXY"]="http://my.proxy.address"
os.environ["HTTPS_PROXY"]="https://my.proxy.address"
This seems to work because I can indeed access the internet through e.g., requests.get, but probably the proxy isn't set at the right scope.
What else should I try?
