Nagios Support Forum

Hello,

Not sure when it started, but I noticed recently that some of the administrative pages are completely blank. I verified that I'm still an admin user.

Clicking the Administration tab on the main page results in a blank page: https://calcium.colo.example.com/nagioslogserver/admin

Clicking on either of the system status icons at the top works, and I can access most admin functions from there, but two don't work:

• Cluster Status, https://calcium.colo.example.com/nagios ... in/cluster
  Index Status, https://calcium.colo.example.com/nagios ... dex_status

I am running NLS 1.4.2; I've tried this on both Firefox and Safari with a cleared cache.

Can you show us the output of:

Does restarting the elasticsearch service solve the issue?
Can you also share the output of the following:

Restarting Elasticsearch has no effect.

I've attached the output you requested since it is very long.

Let's take a step back, since you're using SSL, could you post these two?

Does this KB article help resolve the issue?

https://support.nagios.com/kb/article.php?id=132

That fixed it! Thanks!

Awesome! Is it alright if we lock this thread and mark the issue as resolved?

Yes, thanks
