Trying to activate new device- Cant connect at+wdss=1,1

Hi All,
I have had good luck so far trying to register a new device on the online portal. But when I try to use the at commands to initiate communication from the device to Airvantage, I cannot seem to connect get the expected wdsi response codes:

+WDSI: 4

+WDSI: 5

+WDSI: 8

I checked my apn name and can connect using cm data connect.

root@fx30s:~# cm data info
Index: 1
APN: nxtgenphone
PDP Type: IPV4V6
Connected: yes

root@fx30s:~# ping

My target device is FX30S. With the following firmware and bootloader:
Firmware: SWI9X15Y_07.11.22.00 r33729 CARMD-EV-FRMWR1 2017/01/11 18:04:06
Bootloader: SWI9X15Y_07.11.22.00 r33729 CARMD-EV-FRMWR1 2017/01/11 18:04:06

This has previously worked for other FX30 devices which I have but all of a sudden its not working now. Trying to do a customer demo here. Has someone seen this happen before.

Hey virajpadte, I’ve been looking at the forum for a while now and haven’t seen anyone else who is having this issue. It would be great if someone would be able to address this problem, because in its current state, I don’t believe that I can fully rely upon AirVantage as a cloud platform. I hope someone from Sierra can rectify this soon.

it’s possible that communications are blocked by the firewall.
it should be configured by following the description of the FX30s User guide;
refer to chapter “Reconfiguring the Firewall”;
best regards
