urllib2.URLError: urlopen error [Errno 8] _ssl.c:480: EOF occurred in violation of protocol

i don't know why

PS:i live in china,and may be because of the GFW. and when i use the type :appengine.google.com and then input the password,i can开发者_如何学编程't redict to the index page,there is an error too,which says:ssl error

As per this SO question, the issue is discussed here and the solution is to set proxies, e.g. in Windows on the command line:

set HTTP_PROXY=http://google.cn:80 
set HTTPS_PROXY=http://google.cn:80 

(or however you set proxies for http and https on your platform, which you don't mention).
