Nginx config error: [emerg] 1226#0: duplicate location

I’ve been getting web socket errors in the browser console so I added to my site’s Nginx config file, some code a fellow posted here: http://stackoverflow.com/questions/17014969/meteor-websocket-handshake-error… But Nginx did not approve. The site isn’t responding in the browser and it says “fail” when I try to restart the Nginx service after removing the new code from the config file. There’s this error in /var/log/nginx/error.log:

2015/04/18 21:09:57 [emerg] 1226#0: duplicate location "/" in /etc/nginx/conf.d/loyr.conf:14

And this is the Nginx config file for the domain /etc/nginx/conf.d/loyr.conf:

server {
 listen 80;

 server_name loyr.co;

 location / {
 proxy_pass http://localhost:3001;
 proxy_http_version 1.1;
 proxy_set_header Upgrade $http_upgrade;
 proxy_set_header Connection ‘upgrade’;
 proxy_set_header Host $host;
 proxy_cache_bypass $http_upgrade;
 }

}

Any ideas? Thanks!
