Server Error 502 with Node.JS + PM2 + NGINX

I managed to deploy my Node JS API working on my server via digital ocean, and it works great—for a few hours. I can run queries from a GraphQL client and get responses just fine. But, after a few hours (usually overnight), it stops functioning and gives a 502 error at my website instead. How do I work around and debug this error? Any help is appreciated!

Hi there,

It sounds like your app has stopped working or crashed for some reason.

You can restart it with:

  • First get your app ID:
pm2 status
  • Then restart it:
pm2 restart APP_ID_HERE
  • Then also make sure to check your logs to see why it has crashed in the first place:
pm2 logs APP_ID_HERE

Let me know how it goes!

Best,

Bobby
