NSURLErrorDomain -1004?

Hi, i installed Home Assistant on one of my raspis. all ok ecept i am not able to login.
Error Code is:

NSURLErrorDomain -1004

with the app on iphone 10

Can anyone help?

It is a headless system but i also tried it with a monitor. but monitor stays black.

I have the same problem. Just installed on a Yellow board and can’t connect via app on iphone or desktop web browser. I can find several references to NSURLErrorDomain -1004 in the forums, but all without answers…

Update: Okay, not quite accurate, there are a couple of replies to two posts, but no solutions…
