Dashboard Not Found

[Giosue]

After spending some time on the dashboard (around 7–15 seconds), I get the error:

“Dashboard Not Found
The specified dashboard was not found. Redirect to your default dashboard.”

When I click on “redirect,” it works again, but only temporarily — the error reappears after another 7–15 seconds.

I use only the standard dashboard and I've never saved other dashboards.

Can you hit F11 while you're in your browser, and post the URL (feel free to redact your IP address) of the item that shows the 404 error while its loading dashboards?

So this is the dashboard URL I go to when the pop-up appears: https://fqdn/nagioslogserver/dashboard
Using the developer tools, this is what is shown:

That's very unusual and unexpected. Can you log in as a different user and look at a dashboard? Or navigate to http://fqdn/nagioslogserver/dashboard?d ... id=default

When using another user (AD user), everything works flawlessly.
However, with the local admin account, the error still persists.
Even when accessing the following URL: http://fqdn/nagioslogserver/dashboard?d ... id=default

When you say that another user can see the dashboard, are you looking at the same dashboard or a different one?

ALso out of curiosity, how old is this Nagios Log Server deployment?

It is the same one and we only work on this instance.
The deployment dates back to June 2025 and has been updated multiple times since then.

Unfortunately I'm beginning to think that this is deeper than what we can dig into on the forum here. Do you have active support where you can open up a support ticket for this? They'll have a better ability to work with you to track this down better.

Yesterday, I noticed that the only difference between the account that worked and the one that didn't was the Dashboard mode.

So, I changed the Dashboard mode on the account that wasn't working from "Advanced" to "Simple". After 24 hours and a new login, it worked flawlessly.

That's great to hear!
