Asked by Yuri
Hi,
DOCN rebooted by droplet and now I am getting a 502 Bad Gateway error (nginx/1.18.0 (Ubuntu)). Please could someone assist what I need to do. I tried running “pm2 restart app.js” in console but getting [PM2][ERROR] Process or Namespace app.js not found.
This is really frustrating as my service is down because of Digital Ocean issue - have raised a support ticket.

Heya @yuriwhale,
When you do
Do you see your application? Try to start that one, otherwise go to yur App’s folder where the
app.jsis and try to start the pm2 process from there.Addtionally, check pm2 error log, you can either do
or go to pm2 logs and check the error log for more detailed response.
Hey @yuriwhale,
First you can check that pm2 is running. Run
pm2 statusto see if your application is listed there. If it’s not listed, you’ll need to start it again.If your application is not listed in the PM2 status, you can start it by running
pm2 start app.js. Make sure you navigate to the directory where yourapp.jsfile is located before running this command.After starting your application, monitor the logs to see if there are any errors. You can do this by running
pm2 logs.Another thing is to check if NGINX is running and if not to restart it.
If NGINX is down, then you can restart it.
Hope that helps!
