Is the DDNS IP up-to-date?
Check:
curl -4 ifconfig.io
Nothing is listening at the moment [on 80 or 443]:
curl http://studiodomotico.duckdns.org
curl: (56) Recv failure: Connection reset by peer
curl https://studiodomotico.duckdns.org
curl: (7) Failed to connect to studiodomotico.duckdns.org port 443: No route to host
