SSH problem on windows

I have mercurial set up with ssh on windows XP. As ssh client I use plink

Here's my .hgrc

{{

{ [ui]\\ username=Evgeniy Sharapov [evgeniy.sharapov%40gmail.com]\\ ssh=C:/tools/putty/plink -ssh -i "C:\Documents and Settings\xxxxx\Application Settings\ssh-private-key.ppk" [http_proxy]\\ host=some.proxy.server:8080\\ server.\\ passwd=xxxxx\\ user=xxxxx }

}}

When I do push

{{

{\\ C:\Temp\conf-emacs>hg -v push ssh://hg@bitbucket.org/evgeniysharapov/conf-emacs/\\ running "C:/tools/putty/plink -ssh -i "C:\Documents and Settings\xxxxx\Application Settings\ssh-private-key.ppk"\\ hg@bitbucket.org "hg -R evgeniysharapov/conf-emacs/ serve --stdio""\\ remote: FATAL ERROR: Network error: Connection timed out\\ abort: no suitable response from remote hg! }

}}
