Complete new setup:
New HW, new SD cards, current image (openHABian v1.6.5.), for details please see screenshot.
After starting OH3, I created a new user with the web front-end which results in a empty grey screen. With a browser reload the setup continues and I can start configurations.
But: after a reboot the login fails now every time and I never get the settings menu (see screenshot below).
In the log file there are coresponding entries (see screenshot above).
I repeated the installation with different SD cards and different original images (the current and older ones), and I tried different browsers (Safari iPad, Firefox under Windows 10 and Ubuntu), every time with the same behaviour.
Open web front-end en privacy mode of the browser or a different IP address for the server don’t change anything
Thread https://community.openhab.org/t/empty-gray-screen-after-login-oh3/115346 doesn’t help, no camera, no widgets.
Any idea / help welcome.
