ServerTransferServersWhitelist setting does not appear to function

You can look at the Game.ini in the ConanSandbox/Saved/Config folder as mentioned here:

Battlemetrics is also an option, it lists the IP address for the Conan officials that have been added to it, but it only works for older servers so I wouldn’t recommend it. Simply go into game and favorite the officials and then you can see their IP addresses in the Game.ini to use in Server Whitelist.
