Redmine

Hi.
I've a redmine 1.3.2 install on Ubuntu 12.04. I'm using Gitosis as SCM, and https://github.com/ericpaulbishop/redmine_git_hosting plugin for that.

I've been using this for long time without issue. Today I was asking a collegue to clone the repo via http and it failed. I tried on my PC where I use it via git+ssh and via http I get the same error:

fatal: http://maxxer@MY_HOST/redmine/project.git/info/refs not valid: is this a git repository?

I tried accessing that link in my browser and, after auth, I can see the branches and their hashes.

Two odd things:

• issuing the same command in the LAN where the redmine server resides completes successfully
• I have a remote server from which I cloned months ago using http, pushing and pulling and cloning from there works great!

how's possible? expecially the last. apparently there's a host limit for clone? But I can't recall or find where this setting is!
any help is welcome.

thanks
