Fix "502 Bad Gateway" message from nginx

[seven1m]

When OneBody is restarted, nginx by default will return "502 Bad Gateway" to the user while the backend process is coming back online. I think there must be a setting in nginx to make it wait for the backend service to come online.

This makes me think the built-in proxy_pass in nginx can't do it:

I cannot find a solution for this. Closing.
