Weird preview window bug

i have this weird issue with a specific site on our work network and xibo. i made a layout that has shows a website that is locally hosted on our network but every time i try to edit or preview the layout it imediatly goes directly to the site and leaves xibo.

ps: i have also tried to use this layout and it just gives me a blackscreen.

Did you try to embed this site in an iframe in embed html in Xibo?
