GTID chain replication setup

Hello,

We already have 3 MySQL servers in chain replication using gtid. A-B-C where B is slave of master A, Slave B act as master for slave C.

We are creating a DR setup with same config as Primary. DR master will point to Primary master A. But when we restore dump taken from primary master, replication between DR master and DR slaves breaks with error 1236 binary log is purged. What is wrong here? Any pre requisite before we restore?
