on my server1 , I run nginx as reverse_proxy to server2 which is running a node.js app on port 3000 ( full MEAN stack)
when I start server2 with grunt, everything is running fine
-- server2 ---
cd /opt/mean
grunt # running server.js , MEAN app
as a next learning step, I am trying to use pm2 on server2 to monitor my test web app . I installed pm2 and run
-- server2 ---
cd /opt/mean
pm2 start server.js
and got
[PM2] restartProcessId process id 0
[PM2] Process successfully started

When I try to request my app in the browser , I get now an error from server1
502 Bad Gateway nginx/1.4.6 (Ubuntu)
Do I have to add or update anything into the nginx default config, as the proxy_pass directive is pointing to http://:3000
many thanks for your feedback and Happy New Year 2016 !
That "pm2 show" is showing that your node server errored, so it's probably not running. What do you see if you tail the error log? It should have some details in there about the issue
The proxy error I think is possibly because node isn't running
