Get this error when trying to create repo. bzr: ERROR: Connection error: while sending POST /bazaar/: [Errno 10060] A connection attempt failed ..

Hello,
           I am a new user of bazaar and was trying to setup a repo. I am sorry if this has been addressed before , but I could not find a complete that I am looking for and so decided to post this question

I started with

http://doc.bazaar.canonical.com/latest/en/mini-tutorial/

However trying to copy a branch, I get an error

$ bzr branch lp:~bzr/bzr-gtk/trunk ~/bzr-gtk/

bzr: ERROR: Connection error: while sending POST /bazaar/: [Errno 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond

I am using a Windows 7 system. I first tried this on my office network which does use a proxy.

I came across

http://doc.bazaar.canonical.com/latest/en/user-guide/configuring_bazaar.html

but I am not sure what exactly 'user's profile' means on Windows. Do I need to setup http_proxy and https_proxy as system variables or put them in some file ?

I tried

$bzr config http_proxy=<proxy>
$bzr config https_proxy=<proxy>

but that did not work.

So I just want to figure out how do I setup the proxy requirements ?

Thank you.
