hg clone using mercurial throws "getaddrinfo failed" error (windows 7)

Sounds like you might need to tell Mercurial what your proxy settings are. First hit for "mercurial proxy":

If you need to figure out what settings to use, you should probably look at what your IE settings are, e.g. by going to the Internet Properties | Connections | LAN Settings dialog.

Just remove the http_proxy environment variable. (worked for me, after of 5 hours of headache).

If you find yourself on this page because you've hit a getaddr error when using the hg-git plugin with a username, it is likely that you've hit the Fails with username in URL (getaddreinfo failed) bug.

Thus:

$ hg clone https://foo@stash/
abort: error: getaddrinfo failed
$ hg clone https://stash/
http authorization required for http://stash.....
realm: Atlassian Stash
user: ...

(Doesn't solve the original user's issue, but can be a cause of the same symptoms).

Pls check whether you can access the repository directly first. e.g from web browser
