Submodule update -> authentication failed

I forked a copy of blender on Cloned it and ran ‘make update’. It passes through the svn and rebase steps. When it does the submodule update step, it asks for username and password (hasn’t before). I enter what I use to login to projects, and I get a ‘fatal: Authentication failed’, and it gets stuck in a loop asking for username.

Suggestions on things to try?

did you clone your own fork, or did you clone ?

it needs to be the main blender repo, not your personal fork, and then you follow these instructions to configure your personal fork as a remote

Cloned the fork. I’ll try it the right way and RTM next time. (I did, I just kind of ignored it and set it up like most git repos I’m used to).
