502 Bad Gateway errors from Nginx when trying to access Tomcat

[gischethans]

Yes, I followed the instructions as-is and they work. The problems begin
when I block Tomcat from listening to external IPs by adding
address=127.0.0.1 in the Connector blocks. The Atlassian guide does not
discuss that aspect at all. 

>From what I have observed, I feel that even if I have a Nginx reverse proxy,
the requests are handled by Tomcat if one follows Atlassian's documentation.
