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 b...

Or navigate to http://fqdn/nagioslogserver/dashboard?dashboardid=default When using another user (AD user), everything works flawlessly.

As for the rsyslogd message, where is it coming from...

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, thi...
