Hello. I installed Nextcloud with Letsencrypt on the basis of this guide :https://www.youtube.com/channe…PA?feature=emb_ch_name_ex
and I have a problem. When I type in https://mydomain.duckdns.org using my phone with turned off WiFi It is working like a charm. But when I type in same adress with WiFi turned on I see my router website. If I have done port forwarding for example port 9000 (only for testing) and i type in mydomain.duckdns.org:9000 with WiFi on, I see Portainer website. So I think Nexctcloud with Letsencrypt must be running on different port. I'm right? Can anyone help me?
