Authorizing with GitHub/Space from TeamCity on premise

Hi,

When trying to authorize with GitHub or Space when adding a project it opens a windows with local URL like these:

http://localhost/oauth/space/repositories.html?projectId=_Root&connectionId=PROJECT_EXT_2&vcsType=&updateToken=true&showMode=createProjectMenu&userId=1

http://localhost/oauth/github/repositories.html?projectId=_Root&connectionId=PROJECT_EXT_3&updateToken=true&showMode=createProjectMenu&userId=1

But there is no such endpoint on the machine where TeamCity is installed.

Is it possible to authorize with external services on premise?
