Patchbox on Raspberry Pi 400

I run Patchbox OS on Raspberry Pi 400 from ssd. the installation of MODEP seems succesful, no error messages. But I cannot get MODEP running.
I can ping 127.0.01 successful but cannot connect or http://patchbox.local/ from Chrome or Firefox browser.
What did I wrong? What can I try next?

Check if the essential services are running and that Jack is running, if not, try reconfiguring jack via patchbox command:
