Nginx + UWSGI + Flask 504 gateway timeout error

I have a problem with nginx+uwsgi.I am getting 504 bad gateway error exactly after 60 seconds after calling Flask Rest API. Following are the contents of some nginx configurations.Am I missing something or Do I need to make any changes in config files

/etc/nginx/conf.d/nginx.conf content

server {
    listen 6611;
    #ssl_certificate /cert/host.pem;
    #ssl_certificate_key /cert/host.key;

        client_body_timeout 3000;
    }
    location @app {
        include uwsgi_params;  
        uwsgi_pass unix:///tmp/uwsgi.sock;
    }

    location /static {
        alias /static;
    }
}
