Portal Authentication issue

DaleHarris3 — Mon, 03 Nov 2025 00:33:11 GMT

When authenticating with username, password and 2FA I get the following error message after entering my 2FA token.

Exception: A general error occurred: 'EsriBuiltInAuth' object has no attribute 'proxies'

This looks like a bug, does anyone else get this?

Hey @DaleHarris3

Need some additional information from you about this:

Enterprise or Online, if Enterprise which version

What version of Python?

What version of the ArcGIS API for Python?

Is this run in Pro, ArcGIS Notebooks, or standalone IDE?

Hi Cody,

Sorry about that I do normally like to provide more information. I am using ArcGIS Online and I am using version 3.11.11 of python. I am using v2.4.1.1 of ArcGIS API for Python SDK.

I have tried this in both a standalone IDE and Pro (3.5).

Cheers,
Dale

@DaleHarris3 @CodyPatterson
I have the same error when trying to connect to ArcGIS Enterprise 11.3 / 11.5 via a Python script using Python 3.11 and the ArcGIS API for Python 2.4.1.1. Did you find a solution?
