SSLError in Nuke 10.5

Pipeline Integrations
1

Hi, I got the following SSL Error when opening Nuke 10.5 from Shotgun Desktop, using the default latest config. This does not happen with Nuke version 11 or 12.

So I guess this is related to some python version httplib2 incompatibility? Any Help how to solve this, or monkey patch python ssl in nuke 10.5 will be appreciated, thanks!

Hi @macbeth,

The issue you are seeing is because Nuke 10.x is not TLS 1.2 compliant, The Foundry didn’t backport 1.2 support for that Version unfortunately. You can read more about TLS here; https://support.shotgunsoftware.com/hc/en-us/articles/360009371913 .

Hi!! I managed to upgrade SSL in Nuke 10.5v7 in a hacky way, it is working fine so far.

I saw in this post that using a gateway could be a solution, but for me that required work from the IT department and changes in the network, so I prefer another solution.

I saw that Foundry’s official solution to upgrade SSL in Flix, was just to overwrite ssl.py and _ssl.so library.

So I try the same in Nuke I copied SSL 1.0.2 from my systems installed Python 2.7.5 to nukes 2.7.3 and it actually make the trick it is working fine so far.

sudo cp '/usr/lib64/python2.7/ssl.py' '/usr/local/Nuke10.5v7/lib/python2.7/ssl.py'
sudo cp '/usr/lib64/python2.7/lib-dynload/_ssl.so' '/usr/local/Nuke10.5v7/lib/python2.7/lib-dynload/_ssl.so
