Nginx auth before return - nginx

Question

Im using nginx with auth.
All auths works properly in the locations is set, but I have a location /marathon that return same url with other port. I have added auth to this location, but it does not work. I think is regarding to the return directive but I dont know why and how to handle it or solve it. I've been searching but I can't find nothing about this
Any ideas why or how to handle it?
