So, disabling IPv6 solved the loop issue:

```auto
nmcli con mod BRA-BrTCelular-d8a338232cefff166e10be70b28cdf24371041dc ipv6.method "disabled"

```

But its a shame I had to do this, since @aleksander0m mentioned newer versions of ModemManager has this fixed. Is there any kind of release cycle? He asked it here [Which versions of ModemManager and NetworkManager does BalenaOS runs? - #16 by aleksander0m](https://forums.balena.io/t/which-versions-of-modemmanager-and-networkmanager-does-balenaos-runs/346012/16) but didn’t get any response.
