Unable to access web browser for NagiosNA

We recently downloaded NagiosNA for a proof of concept. I am now at a point where I would like to start configuring network devices to send their NetFlow data to NagiosNA.
Currently I am unable to access NagiosNA via the web browser, but I can access the CLI. I was able to access it via the web browser for the last two weeks, so I am not sure what happened.
Does anyone have any suggestions? Better yet, can anyone assist me with resolving this issue?
Thanks,
Mike

try:
Code: Select all
service httpd restart
service mysqld restart
When you access the page is there any error in the browser console? Try reloading the page to see if one is generated.

It just says...Internet Explorer cannot display the webpage
Since I don't have much configured currently, should I just blow the VM away and start from scratch?

Yes, you can start from scratch. Before you do this, can you try a few things. Restart the VM and see if you will be able to log in. Make sure you are using the correct IP address. Check the IP by typing the following command in terminal:
then try to log in web UI by typing in the browser's address bar:
If you are still not able to access the web UI, run the following command and show us the output in code wraps:
Code: Select all
tail -100 /var/log/httpd/error_log

Yes I did try restarting the VM, but that didn't make a difference.
We ended up reinstalling the OVA file/starting from scratch, and now I'm able to access NagiosNA via the web browser.
Thanks for the help.

I just had NNA uninstalled/reinstalled (last week Tuesday) and now today I am unable to access it via the web browser.

So what has changed on the NNA server since you redeployed it?

Nothing really, I added a "test" switch within NNA last week Friday. I confirmed I was able to access NNA earlier today via the browser, and now this afternoon I'm not able to access it.
I get a timeout when I try to ping the associated address.
