Dropdown menu duplication with the Nagvis module

Hello,

I have an issue with my Nagvis module. When I try to open it from my IcingaWeb2 interface, the menu window on the left duplicates, as shown in the screenshot.

I’m on Debian 12

Thank you in advance for your help. If you need any additional information, please don’t hesitate to ask.

I’d recommend opening an issue on github:

I still think you have some strange apache2/nginx redirecting config in place. the url that the nagvis module is trying to reach is:

/nagvis/frontend/nagvis-js/index.php?mod=Map&act=view&show=demo-overview&header_menu=0

and somehow this redirects to your icingaweb2 instance which causes this issue.

http(s):///nagvis/frontend/nagvis-js/… should be provided by the nagvis installation and not be redirected to icingaweb2.
