Hi,
i have some problem with my v5 probe #64441 (firmware 5080). similar with your problem, my probe stuck in registration (reg1/reg2) status to ctr-dub-hw02 (not connect to controller)
here my posting a few weeks ago
already create ticket but nothing from their side they can do regarding the probe.
i tried disable ipv6 dan use ipv4 only, but same result. for now i’m desperate and next will try replace the probe, and i already contact the ambassador that give me the probe.
Thanks
