Iframe doesn't work in server web

Hello, I am new here, and I am trying to iframe the web server into my obsidian for more convenient manipulation. But it only works before I log in.

And after that, it doesn’t show up anything.

I have no idea what the problem is.

The web application does not run in an iFrame

Welcome @Shuusei

It’s unclear where the specific issue is at the moment but it would be better to access web sharing in a browser as designed.
