well, i solved it by accident. I've switched the position of the url in the urls.py like this: Before:

from django.conf.urls import url, include
from django.contrib import admin
from django.views.generic import TemplateView

from rocket import endpoints as endpoints_rocket

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^rocket/', include(endpoints_rocket)),
    url(r'^', TemplateView.as_view(template_name="index.html"), name='home'),
    url(r'^auth/', include('rest_framework_social_oauth2.urls')),
]

After:

from django.conf.urls import url, include
from django.contrib import admin
from django.views.generic import TemplateView

from rocket import endpoints as endpoints_rocket

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^rocket/', include(endpoints_rocket)),
    url(r'^auth/', include('rest_framework_social_oauth2.urls')),
    url(r'^', TemplateView.as_view(template_name="index.html"), name='home'),
]

If someone know why, i'm waiting your explanation \o/
