Nagvis - Geomap | Different tile map servis not working

CMK version: Checkmk Raw Edition 2.2.0p16
OS version: Ubuntu 22.04

Instead of changing the openstreet map behind the nagvis map in checkmk, I want to use my own tile service with {z}/{x}/{y}.png extension. To do this, I change the tile service to my own service from the settings, but the map stops working. When I run my own map service elsewhere, there is no problem. My map works, but I have this problem with nagvis, which works with checkmk.

Is there anyone who changed it before? Can you help me why my own tile service is not working?
