If you use DDNS you need to have a public Internet IP address. In most cases, the mini router is used behind another router so DDNS actually doesn’t work at all. You need to use port forwarder. Even you do this, your ISP may block incoming data.
If you want to use DDNS, you can use other DDNS services. There is a luci package called luci-app-ddns which you can use to set up different DDNS services.
