Not sure if anybody is experiencing this or not, but it is new to me. I would say that this script had worked in the past, but is failing now.
I am simply trying to log into our Portal which is Windows authenticated. I pass in the line below:
gis = arcgis.gis.GIS(r"https://hostname.net/portal/","user.id","password", verify_cert=False)
Returned is: A general error occurred: unsupported hash type md4.
