-6. If you want to be sure Nextcloud gets set up correctly, it is best to perform the remaining steps from a **different** computer.
+6. On a computer that is **not** the device running Nextcloud, launch a browser and point to the device running Nextcloud using your chosen connection method. Examples:
 
-	That means you need to decide how that **other** computer will refer to your Raspberry Pi running Nextcloud. Your choices are:
-
-	* the IP address of your Raspberry Pi – eg `192.168.203.200`
-	* your Raspberry Pi's fully-qualified domain name – eg `myrpi.mydomain.com`
-	* your Raspberry Pi's host name – eg `myrpi`
-
-	Key points:
-
-	* You **can't** use a multicast domain name (eg `myrpi.local`). An mDNS name will not work until Nextcloud has been initialised!
-	* Once you have picked a connection method, **STICK TO IT**.
-	* You are only stuck with this restriction until Nextcloud has been initialised. You **can** (and should) fix it later by completing the steps in ["Access through untrusted domain"](#untrustedDomain).

-7. On a computer that is **not** the Raspberry Pi running Nextcloud, launch a browser and point to the Raspberry Pi running Nextcloud using your chosen connection method. Examples:
-
-	- If you are using an IP address:

-9. There is a long delay. In most cases, the "Recommended apps" screen appears and you can ignore the instructions in this step. However, if your browser returns a "Not Found" error like the following:
-
-	![Mal-formed URL](./images/nextcloud-malformedurl.png)
-
-	then you should:
-
-	* Examine the contents of your browser's URL bar. If you see this pattern:
-
-		```
-		http://localhost/index.php/core/apps/recommended
-		```
-
-	* Edit the URL to replace `localhost` with what it *should* be, which will be **one** of the following patterns, depending on which method you chose to access Nextcloud:
-
-		* `http://192.168.203.200:9321/index.php/core/apps/recommended`
-		* `http://myrpi.mydomain.com:9321/index.php/core/apps/recommended`
-		* `http://myrpi:9321/index.php/core/apps/recommended`
-
-		Note:
-
-		* This seems to be the only time Nextcloud misbehaves and forces `localhost` into a URL.

 Nextcloud traffic is not encrypted. Do **not** expose it to the web by opening a port on your home router. Instead, use a VPN like Wireguard to provide secure access to your home network, and let your remote clients access Nextcloud over the VPN tunnel.
 
+The IOTstack service definition for NextCloud reserves port 9343 for HTTPS access but leaves it as an exercise for the reader to figure out how to make it work. You may get some guidance [here](https://youtu.be/qlcVx-k-02E?si=qtVNFAvSB8w202Jh).

 ## Container health check  { #healthCheck }
 
 A script , or "agent", to assess the health of the MariaDB container has been added to the *local image* via the *Dockerfile*. In other words, the script is specific to IOTstack.
