The login URL that you were sent no longer exists because you've connected your GoDaddy URL to Limefunnels.
So, in order to login moving forward you will use your GoDaddy URL with /login added to the end of the URL.
Original Login: janedoe.limefunnels.com/login
GoDaddy Domain: janedoe.com
New Login: janedoe.com/login
Your username/password will be the same.
