Hi @adavidoladele,

Most probably there is some issue with your NodeJS backend code. Usually, when it stops after 30 seconds or at some point like that it’s because it hit code that it couldn’t execute thus failing. I’ll recommend checking out logs for your NodeJS app, try running it manually and not with the service pm2 to see if it loads and whether it would fail at some point.

All in all, from everything you’ve described, I can confirm it’s not an Nginx configuration issue but everything lies with your NodeJS app.
