Octopus Pro 446 - RatOS Guide 'Board not detected'

Okay... I managed to flash my Octopus Pro 446 board manually using a SD card, and I have the connection ID.
Trying to follow the RatOS guide from here, but it keeps saying "BIGTREETECH Octopus Pro 446 was not detected". Pressing the "Check board status" button doesn't help, and rebooting/power off/on, doesn't make any difference.

I get the idea with the "setup wizard" generating the printer.cfg from all the pieces in the config folder/sub-folders. But it doesn't seem to work. Is this just because of the Alpha state, and I should just skip the wizard and set up the printer.cfg file manually?
