If you have HTTPS configured to run on a non-standard port (eg 4430 rather than 443) and you have $wgSecureLogin enabled, clicking on the 'login' link does not work.
This is problematic particularly for the 'https' role in mediawiki-vagrant (https://gerrit.wikimedia.org/r/#/c/132702/) since with vagrant, you cannot forward ports < 1024.
