Hello,
I had an DS instance with data. I had problem setting a read only replica.
The master server can connect to the slave but it had problem initialize the slave.
I had tried to use the same method to create another slave instance in the master server
(using a different port)
Replication does not start. The error message is the same.
For both cases, the slave instances are brand new, it is empty without any data.
