Hello @dailychoices2020,

Thanks for reaching out. A 502 Bad Gateway Error is a general indicator that there’s something wrong with a website’s server communication. Since it’s just a generic error, it doesn’t actually tell you the website’s exact issue. I recommend you to first check the Nginx error logs for more information.

/var/log/nginx/error.log

Hope this helps!

Cheers, Lalitha

If you are still getting an error after following all the steps at the link in @Lalitha’s answer, check pm2 is running pm2 list If not, check you’re in the correct directory then pm2 start ./(your-server.js) This is assuming you have installed pm2

i have done this test with this command as well /var/log/nginx/error.log. However i found that there are some controllers in my web Application and routes it’s showing the same way as i have coded but i am getting confused how to fix it
