[FIXED] Failed to generate token

Issue

I wanted to generate a token to be able to work with a notebook from another laptop, but I got the following error:

A/.pm2/logs/jupyter-error.log last 15 lines:

Note: I have crossed out some information for security.

I tried updating the library with pip or conda, but it won't let me update or install the libraries. The following error appears:

Retrying (Retry(total=0, connect=None, read=None, redirect=None, status=None)) after connection broken by 'NewConnectionError('<pip._vendor.urllib3.connection.VerifiedHTTPSConnection object at 0x7f9ce8a9f518>: Failed to establish a new connection: [Errno 101] Network is unreachable',)': /simple/jupyter-nbextensions-configurator/
Could not find a version that satisfies the requirement jupyter-nbextensions_configurator (from versions: )
No matching distribution found for jupyter-nbextensions_configurator

Solution

The solution was to update Python, however there were several work environments with different versions of Python, it was only to configure the work environment and it recognized the libraries.
