502 Bad Gateway DeepLink Issue

Hello all! I am experiencing an issue with the Deeplink module.  We are sending out a link to a form in an email.  When the user is already logged in, the link works perfectly.  However, when the user is not logged in, the user is being linked to a 502 Bad Gateway Error.  I have the DeepLink.LoginLocation variable set to our custom login page (see image).   I've tried to set the DeepLink.LoginLocation variable to blank, '' (single quotes), "" (double quotes). and experience the same issue in all of these instances. Does anybody know how to resolve this issue? Thanks!
