Newly installed Jupyter Notebook, but it won't connect to Kernel

Hi Everyone!

First of all, thank you for your time reading this and helping me out.

I recently installed Jupyter Notebook on my new laptop through anaconda installer (Windows 10). However, my notebook somehow could not connect to Kernel. I have tried different ways found via google search (e.g. downgrading tornado, deactivating VPN/Anti-virus and etc.), but none of them has worked out.

The pop up stated: “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.”

Below is the output from terminal and packages installed.

Thank you for taking your time looking at this. Very appreciated!
