It is a clean installation (provided raspbi script) but unfortunately the default webiste wont load.
With Firefox, Edge, Internet Explorer or any Browser the tab wont finish loading, it says "node-red" as the tab description but the website itself wont come up. I already entirely reinstalled the raspberry pi, without success.

Hi, it just took the pi and launched it locally, it works i can see the landing page come up.
how to configure the listen interface properly?

Thanks

So it does work - good.

Now what IP does the ip have?
Enter ifconfig or ip address in the terminal.

Once you have the IPV4 address - can you ping it?

Lastly try the IP in the browser.

Hi Steve,

the Pi has (as you can see in the screenshot, IP: 192.168.199.30) and the Tab is showing "node-red" as tab description, but the page wont load up and stays white.

I changed the settings.js ui Host to 192.168.199.30, if i try to launch node red locally it works with the new listen address, but as soon as i try to connect from my pc (same subnet!) it shows a blank white page.
there is no firewall or any gateway in between

I dont get it tbh

Thanks

Yeah, i seen the screen shot - I just want it verified.

Hello Guys, i was curious and tried to open the webpage on my mobile phone and it works!
There is no Problem with the Pi, it must be something with my pc/notebook i try to access it.

Thanks i will close the thread!

Hi Steve, i can ping it, i am connected to it via ssh
it is obviously on application layer - ms defender or whatever.
My other windows machine works

Hello to everyone who tried to help me, it was indeed my sophos home web-protection blocking the access, i did not get any notification about it to be blocked. I created an exception and now it works fine.
Thanks!
