so I tried to push some updates onto my repo on github via terminal on Mac OSX 10.8.4 and it doesn't work.

I've been getting the same error many times:

Lillys-MacBook-Air:Yuewei Lilly$ git push origin master error: Failed connect to github.com:443; Operation timed out while accessing https://github.com/lillybeans/Yuewei.git/info/refs?service=git-receive-pack fatal: HTTP request failed

Some background:

1. I've pushed many projects onto github before using terminal (when I was in Canada).
2. I am currently in Shanghai, China, could it be the GFW? But when I was in Beijing, I was able to push projects onto github still.
3. when I do ping github.com:

Lillys-MacBook-Air:Yuewei Lilly$ ping github.com

1. I have ShadowSocks (proxy) turned on. Without it I can't access github.com via browser, with it, I can.

2. also when I do "git remote -v" I see both my pull and push remote repos correctly listed.

Thank you in advance!
