SSL error in Nuke 10.5v5

I have install the shotgun_api-3.3.4 with Python 3.10 to Nuke 10.5v5
I tested the communication to ShotGrid in Python with no problems.
But I tried to test some simple scripts in Nuke, it fails with following errors.
Does anyone got the idea to fix this? Thanks.

from shotgun_api3 import Shotgun

Result:

sg = Shotgun(“https://XXX.shotgrid.autodesk.com”,“api_test”,“XXX”)

Result: Traceback (most recent call last):

Hello,

ShotGrid no longer supports TLS v1.1 and below due to security concerns.
Much of the internet itself has adopted TLS v1.2 as the new security standard.

Unfortunately Nuke up to version 10.5 ships with a Python version and specifically the ssl/tls packages with support for up to v1.1 of TLS.

This means that it can no longer communicate with ShotGrid (or many other Cloud services).

I do remember somebody was able to monkeypatch the Nuke Python library that enabled it to work but I’ve not been able to find a guide on that :frowning:

So to use SG you’ll have to at least be running Nuke 11, or setup a Proxy server that communicates with Nuke on tls v1.1 and to SG with tls v1.2.

I’m sad to here that.
Thanks for your help anyway.

Yes unfortunately the Foundry did not choose to create a patch to make this work.
The responsibility lies with them.

They will tell you to pay for an update the nuke to get it fixed.

Yes, unfortunately Nuke 10 family is no longer supported by the Foundry.
