Localhost refused to connect and open .ipynb file

I’m very new to this so please forgive me if this is a stupid question.

I run into a problem when I try to open a .ipynb file outside of my base environment. In my base environment, it works fine. But in my zip310 it shows as a broken page. I can browse the directories but not open any files:

This site can’t be reached

localhost refused to connect.



I have tried:

  • Reinstalling anaconda
  • Using Miniconda instead
  • Restarting my computer
  • jupyter notebook --debug
  • pip install jupyter
  • conda update --all
  • Disabling my firewall and antivirus
  • Changing ports (defaults to 8888)

When I check the notebook list it is blank:

(zip310) C:\Users\name>jupyter notebook list
Currently running servers:

(zip310) C:\Users\name>

I have spent 6+ hours going around in circles on what is probably a really simple issue. Can anyone help?


I have the same issue, if I find a solution will let you know
