Can't find my NAS326 on my webbrowser

Haga

I have a NAS326 that worked great with my old router. A few days ago I got an ASUS BT8 and now I can't get to the login page on the Zyxel NAS326 at all. I can access the files through explorer but not through the browser, neither Chrome nor Edge. I get the IP address but when I try to log in I get the message "page cannot be displayed". What is stopping me?

What does console say? In Chrome, when the page doesn't display press Ctrl-Shift-C. Then there should open a page with a console log. (And much more).
