Hello!
Just to let you know and help you to save hours of problem solving:
After I did a factory-reset the nextbox had a fast-blinking green led for hours. I couldn’t connect to the https address of the box anymore. So I did a full reflashing of SSD and SD. Same problem.
But the real problem is the wrong signalling! The manual states this:
Green led - Fast-Blink - Nextcloud is starting up (docker starting)
Nextcloud was in fact already started up, just waiting on the http-address instead of https.
After creating the admin account according to the manual, the blinking stopped and changed to solid green.
Best regards
PS: The NextBox rocks!
