MIDDLEWARE = [

SUBDOMAIN_URLCONFS = {
    None: 'django_api_main.core.urls',  # Default URL configuration
    'www': 'django_api_main.core.urls',  # Example: 'www' subdomain

REST_FRAMEWORK = {

I don;t know why,

Note: I did edit the subdomains>utils.py file to:

import functools
try:
    from urlparse import urlunparse
except ImportError:
    from urllib.parse import urlunparse

    from django.contrib.sites.models import Site
    domain = Site.objects.get_current().domain

    prefix = 'www.'
    if getattr(settings, 'REMOVE_WWW_FROM_DOMAIN', False) \
            and domain.startswith(prefix):
        domain = domain.replace(prefix, '', 1)

    return domain

get_domain = current_site_domain


def urljoin(domain, path=None, scheme=None):
    """

    urlconf = settings.SUBDOMAIN_URLCONFS.get(subdomain, settings.ROOT_URLCONF)

    domain = get_domain()

    path = simple_reverse(viewname, urlconf=urlconf, args=args, kwargs=kwargs,

To try and fix another issue, Let me know what is going wrong with ,my approach
