When adopting an existing replication setup using the adoptFromAR option with dba.createReplicaSet() in MySQL Shell to create a new InnoDB ReplicaSet, the operation may fails and shows that the target slave server in the replication can't be discovered or connected. For example:
>> Scenario 1
The master server in replication is running on host master.example.com with the default TCP port 3306. The slave server in the same replication is running on other host slave.example.com with the same TCP port 3306.
The adopting operation fails and shows that the slave server slave.example.com can't be discovered:
Adopt a normal running asynchronous replication using the adoptFromAR option with dba.createReplicaSet() in MySQL Shell to create a new InnoDB ReplicaSet.
