How do i use a browser-rendered terminal?

I started to use Cloudflare recently to reach my server behind a NAT. I have successfully built an ssh tunnel and can now connect to the server with cloudflared on my laptop. But I would like to connect to it directly in the browser. I tried to create a self-hosted application with the same URL but when I went to the URL in my browser it said `This page can’t be found. I tried to tweaks a bit but nothing worked.

I’m new to all of this, so please don’t hesitate to share any potential ideas or suggestions. Thanks in advance!

It looks like you correctly enabled browser rendering in the settings, perhaps try in incognito mode to see if you can access the url?
