What is the value of ALLOWED_HOSTS in settings.py? Your site is serving requests that contain a "Host: www.g3suprimentos.com.br<http://www.g3suprimentos.com.br>" header. Django doesn't recognize this as an allowed host, hence the error.
https://docs.djangoproject.com/en/1.7/ref/settings/#allowed-hosts has more.
