It was the /etc/hosts setting. I changed it, and added the host again to
JavaMonitor and the correct IP came up instead of 127.0.0.1. I also double
checked the reverse proxies and they looked good. However, I was still unable
to get it to work. So…
I decided to get the netbrandeds machine back to its stand-alone web and app
server state. However, after starting the app with the local javamonitor, it
no longer worked either. I now get the dreaded “Application not found on this
server” error when I try to bring up the site. Everything else looks good, and
I was able to re-install the app and start it on JavaMonitor with no errors. I
just can’t navigate to the site. I double checked all the relevant
configuration properties and don’t see anything amiss (they are below), and
this server had been running as a stand-alone web and app server for years with
these parameters.
