MySQL, replicação de grupo não sobrevivendo após uma única reinicialização

Alguém pode ver onde estou errando, pois isso está me levando ao extremo.

Configurei uma instalação limpa do MySQL 8.0.17 no meu laptop Windows 10. Passei por todo o initializeprocesso, entrei e configurei um rootusuário e configurei como um serviço.

O arquivo my.ini contém (entre outros):

port = 3306
server-id = 8306
binlog_format = row
relay-log-info-repository = TABLE
master-info-repository = TABLE
gtid_mode = ON
enforce_gtid_consistency = ON
binlog_checksum = NONE

Até agora tudo bem. Eu log, em tudo funciona.

Em seguida, desligo o MySQL e adiciono o seguinte ao arquivo my.cnf.

#GROUP REPLICATION#
loose-transaction_write_set_extraction=XXHASH64
loose-group_replication_group_name="1587d451-feca-11e8-a7b3-c85b768dc0dd"
loose-group_replication_start_on_boot=off
loose-group_replication_local_address= "127.0.0.1:33061"
loose-group_replication_group_seeds= "127.0.0.1:33061"
loose-group_replication_bootstrap_group=off
loose-group_replication_member_weight=100
loose-group_replication_ip_whitelist="169.254.243.231"

A última entrada foi adicionada porque as tentativas anteriores reclamaram que não estava na lista de permissões.

Eu reinicio o MySQL novamente.

Agora eu começo a configurar a replicação de grupo.

SET SQL_LOG_BIN=0;
CREATE USER 'GReplication'@'%' IDENTIFIED WITH 'mysql_native_password' BY '@Replication123';
GRANT REPLICATION SLAVE ON *.* TO 'GReplication'@'%';
SET SQL_LOG_BIN=1;

CHANGE MASTER TO MASTER_USER='GReplication', MASTER_PASSWORD='@Replication123' FOR CHANNEL 'group_replication_recovery';

INSTALL PLUGIN group_replication SONAME 'group_replication.dll';
SHOW PLUGINS;

SET GLOBAL group_replication_bootstrap_group=ON;
START GROUP_REPLICATION;
SET GLOBAL group_replication_bootstrap_group=OFF;

SELECT * FROM performance_schema.replication_group_members;

Isso mostra um membro ativo.

MySQL  localhost:3306 ssl  SQL > SELECT * FROM performance_schema.replication_group_members;
+---------------------------+--------------------------------------+-------------+-------------+--------------+-------------+----------------+
| CHANNEL_NAME              | MEMBER_ID                            | MEMBER_HOST | MEMBER_PORT | MEMBER_STATE | MEMBER_ROLE | MEMBER_VERSION |
+---------------------------+--------------------------------------+-------------+-------------+--------------+-------------+----------------+
| group_replication_applier | 454b0127-b204-11e9-a032-c85b768dc0db | pc12345     |        3306 | ONLINE       | PRIMARY     | 8.0.17         |
+---------------------------+--------------------------------------+-------------+-------------+--------------+-------------+----------------+
1 row in set (0.0005 sec)

Agora altero a seguinte linha no arquivo my.ini para "on"

loose-group_replication_start_on_boot=on

E reinicie o MySQL.

No entanto, quando eu verifico, agora recebo:

MySQL  localhost:3306 ssl  SQL > SELECT * FROM performance_schema.replication_group_members;
+---------------------------+--------------------------------------+-------------+-------------+--------------+-------------+----------------+
| CHANNEL_NAME              | MEMBER_ID                            | MEMBER_HOST | MEMBER_PORT | MEMBER_STATE | MEMBER_ROLE | MEMBER_VERSION |
+---------------------------+--------------------------------------+-------------+-------------+--------------+-------------+----------------+
| group_replication_applier | 454b0127-b204-11e9-a032-c85b768dc0db | pc12345     |        3306 | OFFLINE      |             |                |
+---------------------------+--------------------------------------+-------------+-------------+--------------+-------------+----------------+
1 row in set (0.0005 sec)

Olhando no log de erros, tudo parece estar funcionando bem até:

2019-07-29T15:26:17.651950Z 0 [ERROR] [MY-011735] [Repl] Plugin group_replication reported: '[GCS] Error connecting to all peers. Member join failed. Local port: 33061'

Presumo que estou faltando um passo em algum lugar, mas o que é isso? Passei por toda a documentação que posso encontrar e não consigo ver nada de diferente?

Eu também tentei configurá-lo no Linux, com o mesmo resultado.
