Cannot connect local to HA green, HA green on network, Access CLI possible,

After updating HA version and OS through the HA interface, i cannot connect any more to the local interface. From the PC i get the below screen, from an iphone phone I get an error code “PromiseKit.PMKHTTPError 0 {}”
Also i can connect to the HA Green by CLI (screen via HDMI and keyboard via USB)
I tried to reload the Core and the OS, no change

Can you connect with a browser?

No, and that is the issue. i get the screen i added to the post.

Aslo in CLI if I do a “core rebuild” the result is “Prossessing done” and next line “Error: No Home Assistant Core response, assuming a fatal startup error”
