Argon blinking red through setting up (new Argon)

Hello just try to setting up a new Argon but after the the input of the WIFI password I receive a Error msg : The Bluetooth connection was dropped unexplectedly.
I search on the community and I flash the new bootloader 1.4.4 same the Tinker but without result.
I run the particle keys doctor this is the answer
C:>particle keys doctor xxxxxxx
New Key Created!
C:>particle keys server
Okay! New keys in place, your device will not restart.

Any suggestions? thanks a lot Valentino
