I just got ahold of a used NanoBridge M2 and installed the firmware. I cannot get past the setup. When I attempt to save the setup, it responds "error saving setup."

If I intentionally make an error - such as failing to enter a password - it responds with a message that indicates I must enter a password. The generic message is not helpful. Has anybody encountered this before?

I also noted that the device does not have the expected IP address but instead has maintained the default UBIQUITI address.

Should I attempt to re-install the firmware?
