Cannot add read replica node

I’m trying to add 1 read replica on a west region to an existing yugabyte cluster in east coast region.
I generated the certicate on the master node for the new ip replica, on master host is xx.xx.xx.96.
/opt/yugabyte//bin/yugabyted cert generate_server_certs --hostnames=xx.xx.xx.46

I copy the certs to the replica certs dir and tried to started the replica the same way I started the other nodes but it errored out.
yugabyted start --secure --certs_dir=/db/yugabyte/certs --cloud_location=xx.xx.rr-1a --base_dir=/db/yugabyte --advertise_address=xx.xx.xx.46 --join=xx.xx.xx.96 --fault_tolerance=region

On the master, I ran the yb-admin command :
/opt/yugabyte/bin/yb-admin --certs_dir_name /db/yugabyte/certs --master_addresses xx.xx.xx.96:7100,xx.xx.xx.101:7100,xx.xx.xx.93:7100 add_read_replica_placement_info xx.xx.rr-1a:1 1 rr

Fetching configs from join IP…

The log has reference the list_all_masters command and looks like it could not run this command.
