Just set up the Freenet6 Tunnel Broker (Authenticated).
Then tried to change the Server Address from "authenticated.freenet6.net" to "amsterdam.freenet6.net" which resulted in showing an internal reference (see screenshot)
And connecting does not work anymore when it shows the reference. Had to save the Tunnel Broker settings again. Then it adds the "authenticated.freenet6.net" address again and it works.
