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:
