the 1 thing see according the docs, url config value should full web-accessible address points nodebb. sporklounge.com, not current value.
it backend responding slowly. try high values of value in nginx see if backend responds:
# testing, allow long response times. proxy_read_timeout 5m; also, use netstat confirm backend running on port 4567:
sudo netstat -nlp | grep ':4567' wait, answer may right in logs, give reason connection failure:
(13: permission denied) while connecting upstream
