Thank you very much for your input. In the meantime I checked the permissions of the app and yes, I have the Internet permission enabled for Android.

Hello all, for an existing client FMX-program I recently had to change the host name as the server is no longer available via an IPv4 adress and instead only at IPv6. Now, I am facing the problem that the program runs well under Windows but gives an exception "No adress associated with hostname" when running under Android. I have changed the IPVersion property of the TIdTCPClient component to "Id_IPv6" and I have successfully checked the IPv6 compatibility of the Android device(s) with www.test-ipv6.com before testing. Has someone of you ideas what could be the problem?? Thanks in advance for your input.
