ISE Server lost WEB Interface connectivity

[Sam_I_Am.]

Good afteroon,

I'm initially building an ISE Server for the first time and I was following an SOP guide provided by another branch office of my organization.  I was able to successfully configure the initial CLI and I was in the middle of researching information to obtain a patch bundle when the web connection to my ISE Server suddenly went down.  Initially, I got a 500 error and that turned into a 403 error.  I tried to ssh into the server through putty, but I couldn't.  I was able to ssh into it from other ISE Server (which is even less configured) and I'm currently looking through the logs to see if I can make anything out.

I can still ping the system, but I'm unsure of how to get the web interface back.

Sincerely,

Sam

With further troubleshooting, I found ip host (null) after the ip default-gateway on my show running-config

The IOS I'm running is 1.3.0.876.

post installation, please validate the service status like below:

ISE/admin# sh application status ise

ISE Database listener is running, PID: 5961
ISE Database is running, number of processes: 42
ISE Application Server is running, PID: 21150
ISE Profiler DB is running, PID: 6922
ISE M&T Session Database is running, PID: 19364
ISE M&T Log Collector is running, PID: 19554
ISE M&T Log Processor is running, PID: 19640

If you still run into issues that you can validate the application logs:

Hi Sam,

Have you gotten this fixed now?

Post the output of the show application status ise command from the CLI.

[Sam_I_Am.]

I actually started over from scratch again because of time restraints.  If the issue comes back up, I'll copy the output you mention and go from there.
