Problems using DDNS inside LAN

Hello everyone,

I’ve set up a Nextcloud server (snap version) in my LAN network. For reaching the server from the WAN, I’ve configured a DuckDNS client. In my router I’ve added forwarding port rules for 80/TCP and 443/TCP.
I’ve also used Let’s Encrypt for generating an SSL certificate and using HTTPS.
Additionally, I’ve added a DNS entry that maps my DDNS address to the static IP of the nextcloud server.

I’ve downloaded the android app of nextcloud and I can reach the nextcloud server using the DuckDNS domain. However, I don’t success in logging in with the phone when I’m inside the LAN. The server gives time out errors most of the time. I’ve achieved log in using the QR code, but still the app is unusable. The resource usage in the server is very low so I discard that it’s performance problems.
On the other hand, using the IP address goes perfect and smooth, but it’s obviously useless for outside the LAN.

Reaching the server from the WAN via DDNS works also totally fine. I must be missing something. Could you please give me ideas of what else have to be configured?

Nextcloud version : 19.0.1.1
Operating system and version : Ubuntu 18.04 LTS
Apache or nginx version : Apache (snap version)
PHP version: (snap version)
