OpenThread Border Router not sending back child ID response

Question

I setup a OpenThread Border Router on a Raspberry PI With EFR32MG12 as an RCP, But Whenever I tries to connect a child Node to my Border Router it Shows Detached State. When I looked In to the Network Analyzer Border Router is not sending back the Child ID Response for the Child ID Request. But When I Tried WithOut a Border Router Iam Getting Proper Responses and state as Child. Just started working on thread my knowledge is very little here.Any Help Please
