Unable to Retrieve Local Issuer Certificate

OscarFitzpatrick — Mon, 30 Jun 2025 10:09:28 GMT

Hi,

When using ArcGIS API for python to connect to our enterprise portal, after setting verify_cert to False, I receive an exception that our local issuer certificate cannot be retrieved, here's the exception in question:

[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1006)

I've searched online, but I haven't found information relevant to this particular exception, and I'm wondering if anyone could advise or direct me to any information or documentation that can assist in resolving this issue.

Hey @OscarFitzpatrick

This may be a warning rather than a direct error, but since I can't see your IDE I can't tell for sure. If it is a warning, you may have luck with the last comment on this post here:

https://community.esri.com/t5/arcgis-enterprise-questions/sign-in-to-portal-via-python-script-creates-ssl/td-p/1570982

Basically, it says to disable the warning message, and set verify false on a few items, better explained in that post, if that still doesn't work, let me know and I'll check it out!

Without showing more of the code that gets you the error, specifically the function/method call, it is hard for folks to provide suggestions. Do you get that message when you instantiate a GIS object?
