Apn connect only gives ipv6-addr

Legato Application Framework
1

I have a WP8548 module. It works great, then at an unknown stage its cm connect only connects as an ipv6. When running ifconfig it shows

rmnet0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00
inet6 addr: fe80::8610:5c:da7f:a8e6/64 Scope:Link

TX packets:678 errors:0 dropped:0 overruns:0 carrier:0

RX bytes:0 (0.0 B) TX bytes:138252 (135.0 KiB)

The setup on
cm data info

Index: 1
APN: csdtecmo.co.za
PDP Type: IPV4
Connected: yes
Auth type: PAP
User name: tecmo
Password: tecmo

I know the IP, and can ping it from another pc, so the device did connect. And when I send the command AT+CGPADDR via /dev/ttyAT, I get the correct IPv4 Address :
AT+CGPADDR

+CGPADDR: 1,10.10.1.2
OK

Running legato version 16.07.0_cd4985660a55cc9a6f9a2ed28bcc757e_modified, as from the FW_Updates. I get the same result, when starting the connection via an application, or via SSH.
