Octaprint connected only on the same network

Hello everyone,
I have a little problem,
I use PI 3B +,
I can only connect to the device when I'm on the same WIFI (same IP address).
Only when I'm connected to the same network does everything work fine,
When I'm on another WIFI or 4G mobile it doesn't work,
Thanks for any help!
