Online Preview doesn't work on cell phone

Hi, when I enable the preview I it's not problem to share the online link with others. But when I try to open it on a cell phone I always get a timeout ERR_CONNECTION_TIMED_OUT

On my Android

Hello! This can happen if you are using the IP address on your phone. This is only available on the PC that Bootstrap Studio is running on. You will need to enter the 192.168.x.x IP address on your phone. Also make sure that you are connected to the same WiFi network.

No, we use the other IP Adress but you answered it: We have to use the same WiFi! Makes sense! :) thx!
