Connection to jupyter notebook server could not be established

I had installed Jupyter notebook on Jetson Nano Dev. Kit. It was working fine. All of sudden it started giving “Connection Failed” error as “A connection to the notebook server could not be established. This notebook will continue trying to reconnect. Check your network connection or network server configuration”.
Kernel is not connecting.
All the updates have been performed. Uninstall and reinstall of jupyter has been done.


I am moving your topic to the Jetson category for better visibility.

Please install Jetpack 4.4 and follow the steps in
