Hello everyone,

I'm trying to set up an "Internet FTP", but for some reason the DDNS info doesn't update/doesn't work. 

The settings under USB > Storage Settings keep prompting me to set up DDNS:

But it's actually configured and I have a bound domain:

The guide lists the same steps I'm doing, but it's not very detailed. So, am I missing something? Or is this TP-Link DDNS service a paid feature which I have to activate or pay for somewhere else?

Thank you for your replies.
