You are getting it because someone has come to your server by entering www.g3suprimentos.com.br in a browser. If you don't have that address in the allowed hosts setting, you will get the error you have received.
If you don't want your server to show something for www.g3suprimentos.com.br, then the problem is not on your end, but rather the clients (it can be an incorrect DNS entry, or that someone has edited their hosts file). So you can't do anything to fix it.
