Thanks. This is what I see (I have discarded the parts that IMHO less important):

I have searched the forums for “code 17 error” and found [this forum entry](https://community.particle.io/t/cloud-handshake-failed-code-17/50132). I have made an attempt to downgrade to deviceOS 1.2.1 but I just got red blinking LED “SOS 10”. Then I switched to deviceOS 1.3.1, that is showing the same signs as 1.4.4 (very same code 17 error on the serial terminal after using your debug code). Then I have again “doctored” the keys and synched to the server, but the result is still the same.

Also on the question of alternative Wifi networks:  
Tried two local 2.4GHz networks with WPA authentication, but very ordinary letters+numbers key. Also tried to initiate a hotspot from my iphone, result did not change.  
I have no idea how to erase the credentials from the device, I presumed that it is just storing the last one?
