Been having problems where my daughters iPad has been unable to connect with the facetime servers to authenticate when on home Vodafone broadband.
Went through a bunch of things with Apple but I've proven it's isolated to the Vodafone network as it works via hotspot to my phone and on other networks.
Have got in contact with Vodafone support but so far no help.
Just wondered if anyone else had seen this or had any ideas on what I could try
