Argon during setting give a Bluetooth error and flashing red

Hi Scruff
could you help me? I post last week a Topic. I buy a new one Argon but I’m unable to setting up.
After enter the network password I receive this msg error:

I read a lot over this error in the community I’m doing particle update ecc… but without result.
I’m not able to change to setup of my router (ip4- ip6) provider don’t give us this possibility. Same to connect other router.
Best regards Valentino
