VMG8823-B50B, V5.13(ABOV.0) how to setup DuckDNS settings

Dino2

I need help to configure the modem VMG8823-B50B, V5.13(ABOV.0)b1_20180824 from Tiscali,

to activate the DNS as "DNS user defined".

Actual settings: (not working)

- "Tipo di connessione:" (connession type), tested both HTTP and HTTPS

- "URL di aggiornamento:" (URL to be updated) here used:

   https://duckdns.org/update/my domain/mytoken

or

  https://www.duckdns.org/update?domains=mydomain&token=mytoken
notice that both strings return an OK when sent via my browser ( the IP is updated).

- "Nome dispositivo ospite" (guest device name?), used http://mydomain.duckdns.org

- "Nome Utente" (username) any string, not requested by duckdns.org

- "Password" any string, not requested by duckdns.org

Notice that both username and password are requested by modem application page.

Thanks for your advice

Dino
