HTTP Error 500 when connecting to portal

ChristopherClary1 — Tue, 18 Jul 2017 21:47:54 GMT

I am able to connect to ArcGIS online, but when we try to connect directly to our portal we receive the following error information. I am new to administering portal and not sure what i could be missing.

from arcgis.gis import GIS

gis = GIS("https://portal.organizationname.gov/mapsrus/", "username", "password")

HTTPError Traceback (most recent call last)

Hello Christopher Clary,

I had the same issue before when connecting to my local portal and the issue was that my portal dosn't have a trusted ceritifcate installed , and to be able to connect through the API I just made set the verify certificate paramter to false and I was able to connect.

So you either need to install a certificate from trusted authority or you can escap certficate validation while connect to your portal by modify your code as the following:

gis = GIS("https://portal.organizationname.gov/mapsrus/", "username", "password",verify_cert=False)
