Here is my nginx file - 

I can get to the frontend at thedailyblech.com/, 
but I can't get to the backend at thedailyblech.com/back/foo. Why?


server {
        listen 80;
        listen [::]:80;

        root /var/www/html;
        index index.html index.htm index.nginx-debian.html;

        server_name thedailyblech.com www.thedailyblech.com localhost;

        location / {
