gitup can't access github repository via https while command line git can

[nilsbecker]

I have a test repo here:

https://github.com/nilsbecker/testgitup.git

which i can clone and then pull from using command line git. however, gitup times out consistently during any remote action. this happens for any remote repository from my computer (not just the test case)

i'm behind a https proxy which is defined as environment variable 'https_proxy' in my shell environment. for GUI apps in macos the system setting 'auto proxy discovery' is enabled. this works fine for the browser and any other app.

is there something i can do find out what the actual connection problem is?

the error pop-up window says:

failed connecting to "origin" remote: failed to connect to github.com: Operation timed out
