I am trying to get a list of items from Sharepoint using Shareplum, but it seems to be giving me an error just by accessing the site:
from shareplum import Site, Office365
from shareplum.site import Version
main_link = 'https://xxxxxxx.sharepoint.com'
whole_link = 'https://xxxxxxxxx.sharepoint.com/sites/TheSiteNeededToRun'
###LINE GIVING THE ERROR###    
cookie = Office365(main_link, username=usr, password=pwd).GetCookies()
###LINE GIVING THE ERROR###
site = Site(whole_link, version=Version.v365, authcookie=cookie)
mnps_list = site.List(mnps_list_name)
data = mnps_list.GetListItems('All Items')
This is the complete error (at the end, it says something about "Shareplum HTTP Post Failed," thus the title):

I suspect of the function .GetCookies(), since I commented almost everything from .GetCookies() to the last line, and ran the module without exceptions (albeit, without the program doing anything, either).
