Hi guys, I want to use the TPlink DDNS service I get from TP-Link Router on my Synology NAS. It asks for a Query URL for this. How should I write this URL?

Hi, i have Deco X20 and Synology NAS DS918+ and i try to configure DDNS in my Synology but it does not have TP-Link DDNS on the list. What query URL should i type in custom adress?
