How to run Jupyter notebook in command line and get full error messages?

My VPN keeps dropping and can not run Jupyter Notebook as it is.

I started to use nbconvert in command line.

But, when it stops due to error, I can not see where the error occurs.

In order to make life easier for debugging, what is the best practice?

Regards,
