upstream api {
server neworleansenglishcourse.com.br:8000;
}
server {
listen 80;
server_name neworleansenglishcourse.com.br www.neworleansenglishcourse.com.br;
location / {
client_max_body_size 8000M;
client_body_buffer_size 8000M;
client_body_timeout 120;
root /usr/share/nginx/html;
index index.html index.htm;
try_files $uri $uri/ /index.html;
}
location /api/ {
