+WDSI:5 authentication with the server failed

Hi,

I have the same issue on my FX30 target.
The at+wdss=1,1 returns me the following:

at+wdss=1,1
OK
+WDSI: 4
+WDSI: 6
+WDSI: 23,0
+WDSI: 4
+WDSI: 6
+WDSI: 23,0
+WDSI: 4
+WDSI: 6
+WDSI: 23,0
+WDSI: 8

The +WDSI: 23,0 indicates a bootstrap session instead of a “Device Management” one and due to that, I connot synchronize my device with airvantage.
I tried to restore the modem configuration with “at&f” without success.

Do you have any idea ?
