Since September 12th, the links on websites (https://deutsche-arkserver.de/, https://www.battlemetrics.com/) or even on the desktop no longer work and generate the error message: "Failure: Unable to connect to server, app id specified by server is invalid". The links are all structured as steam://connect/<server-ip>:query-port>.
The error seems to have originally existed in the beta version of the Steam client and then been transferred to the main/standard Steam version with a minor update on September 11th, 2023.

Current workarounds
URL with RUN
The game can also be started via Steam using the ID, and a server IP & port can be passed through connect.
Syntax:
steam://run/<GAMEID>//+connect%20<IP:PORT>
Example:
steam://run/346110//+connect%2023.88.7.42:17000
The disadvantage is that the game itself must not be started yet. If the game is already running, it cannot be connected to the desired server/IP:Port (and no "error message" will appear) - at least in ARK Survival Evolved. So we should get a solution with "connect" directly from Steam again.
Server Browser
For each server, the following needs to be done once:
1. Close the error message, then the details will be displayed
2. Copy the "<server-ip>:<port>" (e.g. from our cluster 23.88.7.42:17000)
3. Open STEAM and go to "Game Servers" (View->Game Server)
4. Switch to Favorites (top) and click Add (plus symbol) at the bottom/right
5. Add the previously copied content with "ip:port"
6. Now the desired server will appear under Favorites
In addition to the main server "The Island" with Safebase (23.88.7.42:17000), the other IPs are available on the page Server (but in-game cluster transfer is not affected by this).
