In addition to my hosts file issue, when I tried starting my application server for the first time the other day, I ran into an error where everything started except for the JLS which is clearly kind of important. Everything looked fine and the configuration clearly worked on other servers. However, the problem turned out that when I set the application server Jolt settings I entered the machine name which was called 33psapp1. Since the server name starts with a number it gets all upset and thinks that I have entered an IP address when clearly I haven’t. So changing the name to the IP address solves the problem.
You can’t use a machine name that starts with a number in the psappsrv.cfg configuration file. Just simply enter the IP address.
