MYSQL 8.0 - Group Replication - Error on Start up

We are trying to configure group replication in MySQL 8.0 with two machines. We made the following config entries,

[mysqld]
server-id=1
log-bin = /var/lib/mysql/mysql-bin
basedir=/var/lib
relay-log = /var/lib/mysql/mysql-relay-bin
relay-log-index = /var/lib/mysql/mysql-relay-bin.index
relay-log-info-file = /var/lib/mysql/mysql-relay-log.info
max_connections = 1000D

plugin_dir=/usr/lib64/mysql/plugin

datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock

log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

gtid_mode=ON
enforce-gtid-consistency=ON
binlog_checksum=NONE

log_slave_updates=ON
binlog_format=ROW
master_info_repository=TABLE
relay_log_info_repository=TABLE

transaction_write_set_extraction=XXHASH64
loose-group_replication_group_name="f4c300ce-a156-11e8-a825-00e07c7e1047"
loose-group_replication_start_on_boot=off
loose-group_replication_local_address= "192.168.100.183:3306"
loose-group_replication_group_seeds= "192.168.100.183:3306,192.168.100.188:3306"
loose-group_replication_bootstrap_group=off

Also created a new user, gave full permission to that user id and changed it to the master user id using the following command,

CHANGE MASTER TO MASTER_USER='mygroup', MASTER_PASSWORD='######' FOR CHANNEL 'group_replication_recovery';

Then installed group replication plugin using the following command,

INSTALL PLUGIN group_replication SONAME 'group_replication.so';

Then executed the following commands,

SET GLOBAL group_replication_bootstrap_group=ON;
START GROUP_REPLICATION;

At this point we are getting the following error,

ERROR 3094 (HY000): The START GROUP_REPLICATION command failed as the applier module failed to start.

What could be the issue..? Kindly assist...
