arcgis..gisgis.GIS() crashing python when Portal domain has bad intermediate SSL certs

[ohughes16]

Describe the bug We recently had an issue with our domain's intermediate SSL certificates. When instantiating a connection to our Portal using arcgis.gis.GIS(), it would cause the python environment on our server to crash rather than throw any kind of error.

To Reproduce

• You'd need to have bad intermediate SSL certificates
• Attempt to establish GIS object error: No error. Just the entire Python environment crashing on the server.

Expected behavior Any indication of not being able to log in to Portal would have been great rather than crashing the environment entirely.

Platform (please complete the following information):

• OS: Server 2012
• Browser : Edge
• Python API Version: 2.0.0

Have you set verify_cert=False to ignore the invalid certificate?
