The document contains the most commonly useful links to getting started, documentation, how-tos, community information on Python add-ins on ArcGIS Desktop.
Note: Python add-ins are not available on ArcGIS Pro.

I'm seeing is with the live link above, but there is also a link on that page to
https://github.com/jasonbot/addin-wizard
Might want to try that.
fwiw ... some of my tips... https://community.esri.com/thread/74093-tip-python-addins-getting-custom-toolstoolbox-to-work-gptool... (not just that error, btw)
It ended up being a network issue on my end. Thanks for the help
