Help, 502 bad gateway

[Maulana Ibrahim]

Hi, I have a problem that occurs when the 502, I installed the plugin search, and then there is the command to restart so I did, after a long wait I update the browser page and I can 502, so what must be done so that the nodebb can again as before

So this sounds like Nginx is up, but NodeBB is down. Check your logs, what do they tell you has happened?
