I have a web-host connected to my android app, my members can only access the website throw mobile data, not all of them!

What can be the problem? I contact the web-host if there is any problem from their side, everything okay.

I was thinking maybe it's because some routers use IP6 or IP4 and the server only work on one of them!

I have Apache server, but I don't have full access to it, I'm on shared server, How I can check that or add IP6 to my server?
