Suddenly "no connection to Kernel" Windows

Hi, I installed Jupyter via anaconda with my students on their private computers. We did a demo and everything worked last week. This week some 10 out of 60 could not establish a running kernel again. All have Windows 10.

There was a broken symbol where usually python 3 is labelled “No connection to Kernel” and an orange “connecting to kernel” badge next to “Trusted”

Thanking you in advance for your help in this matter.

Cheers,

Sorry you’re having trouble! The main way to debug this is to check:

  1. the browser console, and/or
  2. the terminal where the server is running

These will likely include some errors that hopefully point to a problem. It’s possible a software update caused a package version conflict that’s preventing things from working.
