I can't open jupyter notebook

Hi there,
I have started to set up paperspace a couple of hours ago.
First, I did “git pull” and “conda env update”.
Then I got an error which is like this:

What I did are following after I got the error:
1, pip uninstall notebook
2, pip install notebook==5.6.0
3, jupyter notebook --generate-config jupyter_notebook_config.py “c.NotebookApp.ip = ‘’”
4, jupyter notebook --generate-config jupyter_notebook_config.py c.NotebookApp.open_browser = False

Finally, I got the url to open Jupyter notebook but it didn’t work, when I paste it on Chrome.
Even though, I changed the IP from localhost to mine.

Any ideas?

Solved with following code:
echo ‘c.NotebookApp.allow_remote_access = True’ >> ~/.jupyter/jupyter_notebook_config.py
