(You can call it whatever you want, just ensure it ends in .nginx), and change the path to point to app. As in
# Forward request to /demo to tomcat. This is for
# the BigBlueButton api demos.
location /app {
proxy_redirect default;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
# Allow 30M uploaded presentation document.
client_max_body_size 30m;
client_body_buffer_size 128k;
proxy_connect_timeout 90;
proxy_send_timeout 90;
proxy_read_timeout 90;
proxy_buffer_size 4k;
proxy_buffers 4 32k;
proxy_busy_buffers_size 64k;
proxy_temp_file_write_size 64k;
include fastcgi_params;
}
Then restart nginx.
