[Python] Error of Could not reach host. Are you offline when converting html file into PDF

I am attempting to change an html file into PDF document. I tried multiple methods but none of them proved effective. The html documentwas saved stored on the U drive of my company's network.

For instance, when I am use pyhtml2pdf, I consistently encounter the error displayed below.

https://pypi.org/project/pyhtml2pdf/

from pyhtml2pdf import converter
filepath_html='U:/Data/test.html'
path = os.path.abspath(filepath_html)
converter.convert(f'{path}', 'sample.pdf')

725 # If we're going to release the connection in ``finally:``, then
726 # the response doesn't need to know about the connection. Otherwise
727 # it will also try to release it and we'll have a double-release
728 # mess.
