Jupyter notebook does not run - Please HELP

[etiu]

So I tried a couple of things, like downgrading tornado to 5.1.1 and the uninstalling anaconda and reinstalling it again, but nothing works. The error I get in jupyter notebook is "A connection to the notebook server could not be established. The notebook will continue trying to reconnect. Check your network connection or notebook server configuration." I tried to upgrade pip and then upgrading tornado to 6.0.4, here is the terminal output:

pip install --upgrade pip

Would you have ideas how to fix this? I could not make jupyter notebook work.
