ArcGIS connect to ArcGIS Online fails behind a proxy

Dear community,

does anyone has an idea why my connection to ArcGIS Online will fail behind a proxy?

This is the Python command I am trying:

>>> from arcgis import GIS >>> gis = GIS(proxy_host="myproxy.myorg.at", proxy_port=3128, url="https://myorg.maps.arcgis.com/", username="user", password="password") Traceback (most recent call last):

FYI: It's a known BUG (BUG-000140216) and fixed with ArcGIS API for Python Version 2.0.1.
