Nextcloud setup issue connection refused

hi foks!

i have installed mariadb successfully with docker. And now i wanted to install nextcloud with the docker create command:
docker create --name=nextcloud --net=lsio -e PUID=65534 -e PGID=100 -e TZ=Europe/Berlin -p 8081:8080 -v /storage/.kodi/userdata/addon_data/docker.linuxserver.nextcloud/config:/config -v /storage/.kodi/userdata/docker.linuxserver.nextcloud/data:/data --restart unless-stopped linuxserver/nextcloud

But when trying to access nextcloud “site not found” When curling it i get:
LibreELEC:~ # curl -v -k https://neno.ddns.net 8081

  • Trying 95.208.200.213:443…
