I’m having the same issue as this guy:

Which is, when I run jupyter notebook, I get ERR_FILE_NOT_FOUND in my browser.

It works with the URL but not with the file, because it doesn’t exist.

I noticed Jupyter is supposed to create a new HTML file in %AppData% with a new randomized number every time the local server starts, but that’s just not happening.

I just installed it and this is rather inconvenient.
