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")
