Rewriting / forwarding fritz.box

Hello,

AVM offers the possibility to reach the router via the short URL "fritz.box". The request is forwarded directly to the IP of the router (e.g. 192.168.xxx.yyy).
When using ControlD, this call no longer works, even setting up a user-defined rule with "redirect" does not provide a solution.
What is the procedure - if any - to restore the known behavior?
Thank you!

Best regards
Chris
