Unable to login to Ansible Galaxy

I go here: https://galaxy.ansible.com/login

I click the GitHub logo.

I get redirected here: https://galaxy.ansible.com/accounts/social/signup/

Which completely lacks CSS so it looks a little odd.

I click “Sign In”, which takes me here: https://galaxy.ansible.com/accounts/login/

When I log in there, I get a 500 Server error.
