Since a few weeks (HA 2025-08 ?), my Android companion app doesn't accept new thread device pairing. I reset the device, the pairing window is displayed, then I flash the QR code of the device. Then I've got this error (connect your border router and retry). Of course I've got one : the OTBR of HA which is working fine. I try also to resynchronize the Thread credentials with the companion app and I've this seconde error (An unexpected error occured) :
Any help will be greatly appreciated
