DDNS does not refresh on LTE ME904 router when WAN change

skystef

I activate the wan failover in my ME904.

Primary wan is Ethernet connection and 4G is set to be the backup.

It works fine.

But DDNS update does not work. The IP remains the one of ethernet connexion. When the ME904 switch to 4G, it does not send the new IP to the DDNS service. I try with No-IP and afraid.org.

Anyone can help me ? I have the last firmware. I wait 12h but no update of the IP. I must reboot device ton force update.

Thank you.

LTE ME904 do you mean LTE5398-M904?

Which FW did you use?

If you use the 4G for the primary WAN, will DDNS issue still happen?
