After I upgraded firmware to v2.02 I have problems with DDNS.
After loss of power, reboot or just that the 4G connection goes down and then comes up again, it takes between 1-4 hours before an update of DDNS is done. There must be some kind of bug in Firmware v2.02 with this DDNS service. The practise is that it should trigger an update immediately after the router is online again.
Anyone else with the same problem?
