I I have spent all day on solving this issue and I come here for help. In today’s morning, Jupyter worked really well, and I tried to convert Jupyter to pdf file. But it didn’t work, so I searched the web for help. There was a suggestion to update Jupyter notebook, so I did it. But after this update, Jupyter is not running. I can still access to Jupyter using anaconda prompt. But, when I run the code, it is just not running. When I refresh the page, it says that " This site can’t be reached localhost refused to connect." Here is what I have tried: 1) I don’t think it is related to firewall (I talked with the expert in McAfee); I also tried to set Jupyter notebook password; I uninstall and reinstall multiple times. I need to use Jupyter for my homework, so I am really desperate. I would greatly appreciate if you give me some help! (I tagged wrong before, so I reopen this topic here)
Here is my screenshot.
