UDP with zerotier with different networks

Hi Guys hope that you are doing well :blush:
I have a connection problem with my raspberry pi 4 and pixhawk. I can connect it over zerotier with the same network. It only works when I write the local IP and not managed IP from zerotier. I want to get telemetry over zerotier with different networks to Missionplaner. Hope that you can help me. Maybe I’m missing something :confused:
