Hello, I am reactivating an rpi 4 device, with emteria OS 11.5. I've done this a few times before, it's my development device. But this time it is not connecting to the MDM, I have already activated the option to use MDM, I have already tried to reset the MDM data, I have restarted everything, but nothing resolves it, what could it be? This problem started for no reason. please look at the photo I sent.
