Welcome to the openHAB Forum 
What OS are you using?
Did you by any chance use the openhabian image?
Where do you try to login? Those credentials are for the Karaf console, you would need to login to the OS before that. On an openhabian installation such login would need openhabian/openhabian. Read Here
Openhabian/openhabian worked
Aber ich wollte eigentlich den Openhab Bildschirm sehen
Also funktioniert die Stable nicht mit dem 4B?
In English only, please.
The openhabian image takes sometime in order to install everything. How long did you wait?
Found my mistake!
Not choose raspberry at the download site!
Linux is the default!
can’t select nothing else with my Windows computer.
There is no image for raspberry pi to download!
There you go:
Download and flashing a new SD.
system is still working
