DDNS autorun function

Issue:DDNS service stop after reset

Setup: RAK7240

LoRa® Server:


Dear all,
I have set ddns service on my rak7240. Works fine as soon I will reset it or power off/power on, the service will stop and i need to restart manually trought his own network.
So if it will loose power, after powerup i can’t access from remote via lte network.
There is a way to set an autorun function in dns service?
Thank you

Please, no one can help me to fix this issue?
