"github.com[0: 140.82.114.4]: errno=Connection timed out" indicates either a temporary issue with github (unlikely) or with your network setup.
Already tried a different network path from your dev-machine to the inet? Just to rule out any proxy/MITM instances.

It's also likely that git port is somehow blocked in your setup - try changing "protocol=git" to "protocol=https" in the recipe and check if it is working.
And if have a talk with your IT or internet provider afterwards.
