Port Forwarding, Aviso do Console de Renderização - Rails v4.2.6

Question

Porta encaminhada no roteador local 192.168.1.4:3000 para permitir acesso público com meu endereço IP.

Ao visualizar meu aplicativo rails @ link tudo é exibido corretamente, mas há um aviso de renderização do console de qualquer ponto de acesso diferente de localhost: 3000.

Quando visualizado via localhost: 3000

Se tudo estiver sendo carregado corretamente, por que esse erro no console de renderização está ocorrendo e o que precisa ser feito para corrigir isso?
