Nagvis Error "nagvis.MyFQDN server IP address could not be found."

[KWGagel]

I updated Nagios XI 2026R1 to Nagios XI 2026R1.0.1 yesterday and I just noticed that when I view my Nagvis map I'm getting this error message.
"nagvis.MyFQDN server IP address could not be found." (I've replaced our internal domain with MyFQDN).

What's gone wrong and how do I fix this?

Make sure nagvis.MyFQDN can be resolved.

Obviously "Nagvis" doesn't exist in our internal domain, so it won't resolve. We have never had a DNS entry pointing to Nagvis, are you saying that we need one to point at our Nagios XI server?

I'm not saying anything. Obviously, Nagios thinks it should be resolvable.

Hi @KWGagel,

Just for some clarity, are you navigating to NagVis via XI's UI? Your browser is giving you the error message?

Thanks, Emmett

@ekapsner,

Thanks... In Nagios XI's UI. It was working a couple of days ago but I don't recall checking it after the upgrade so I'm not exactly sure when and why it tanked. This is all I see now.

@KWGagel,

I am having a difficult time replicating this. Where specifically in XI's interface is this link?

The only link to NagVis from XI that I see is <XI's address>/nagvis. Does that URL work on your machine?

Thanks,
Emmett

Replacing /nagiosxi/ with /nagvis/ does bring me to the nagvis maps.
Maybe this is something with the Neptune dark theme.

When I hover of the link I see this.

@KWGagel,

I was able to replicate the issue and it is a bug on our end. I can't promise any timeline for the release of the fix, but when it is fixed, there will be a corresponding line in the Changelog with the tag [GL:XI#2266].

For a temporary workaround, I would recommend bookmarking NagVis with the proper link of <XI's address>/nagvis.

Thanks,
Emmett

Thank you for the confirmation.
