Hello

We have a self hosted 3cx instance and have changed our public IP (change of ISP).

The 3cx itself is ok but the public DNS has not updated, despite doing multiple "refresh license" and a full reboot. I see that the ttl is 10 min so it should have definitely updated...

Is there any way to trigger a refresh ?

Thanks in advance for any advice.
