4. After the initial startup, you should be able to open the Nextcloud AIO Interface now on port 8080 of this server.<br>
E.g. https://internal.ip.of.this.server:8080<br>
If your server has port 80 and 8443 open and you point a domain to your server, you can get a valid certificate automatially by opening the Nextcloud AIO Interface via:<br>
-`80`: redirects to Nextcloud (HTTP) (is used for getting the certificate via ACME http-challenge for mastercontainer)
-`8080`: Master Container Interface with self-signed certificate (HTTPS) (works always, also if only access via IP-address is possible, e.g. `https://internal.ip.address:8080/`)
-`8443`: Master Container Interface with valid automatic certificate via Let's Encrypt! (HTTPS) (Only works if you access the container via a public domain, e.g. `https://public.domain.com:8443/` and not via IP-address.)
