Getting NextCloud going on self-hosted Lint Mint server in Tola attic

(Tues 22nd Sept 2026)

(18:32) DDNS not working..

"The domain is not reachable on Port 443 from within this container. Have you opened port 443/tcp in your router/firewall? If yes is the problem most likely that the router or firewall forbids local access to your domain. Or in other words: NAT loopback (Hairpinning) does not seem to work in your network. You can work around that by setting up a local DNS server and utilizing Split-Brain-DNS and configuring the daemon.json file of your docker daemon to use the local DNS server."

Tenda_D98860 rather than Tola Park router...

(18:15) Tried installing NextCloud..

(18:10) I added portainer to cottage laptop which is current running Home Assistant in docker. This should help run NextCloud.

sudo docker run   --init   --sig-proxy=false   --name nextcloud-aio-mastercontainer   --restart always   --publish 80:80   --publish 8080:8080   --publish 8443:8443   --volume nextcloud_aio_mastercontainer:/mnt/docker-aio-config   --volume /var/run/docker.sock:/var/run/docker.sock:ro   ghcr.io/nextcloud-releases/all-in-one:latest

But failed to install as it needs to contact through port 443. I opened up GL.iNet on http://192.168.22.1/ as shannonclare.zapto.org  and bm9364b.glddns.com but this didn't seemd to helps so more needed. Also lets put in on a server desktop in the attic!
