I am new to Nginx and Ubuntu 16.04. I had an Nginx website up at armadasol.com with a NodeJS script. It uses a local MongoDB and PM2. I made some hard code changes on my home page and after I refreshed the website in the browser, the changes did not update. I restarted my server and now I get a 502 Bad Gateway error.
I have got the PM2 restarted. MongoDB is restarted
I use Nginx, NVM, NodeJs, MongoDB, PM2.
nginx.conf server settings:
Question 1) Why am I receiving a 502 error? Question 2) How do I prevent this next time I make changes in my files? Question 3) Is there a script anyone recommends that can restart my nodejs app when I make changes.
