Hello to all

I use my mysql-router 8.0.32 on Redhat 8.4, the remote dabase is a v8 cluster

Here is the error :

# mysqlrouter --bootstrap myuser@dbp01:3306 --conf-bind-address 127.0.0.1 --account myuser --user mysqlrouter --account-create never --force
Please enter MySQL password for myuser:
# Bootstrapping system MySQL Router instance...

Please enter MySQL password for myuser:
- Using existing certificates from the '/var/lib/mysqlrouter' directory
- Verifying account (using it to run SQL queries that would be run by Router)
- Storing account in keyring
- Adjusting permissions of generated files
- Creating configuration /etc/mysqlrouter/mysqlrouter.conf
Error: Error executing MySQL query "select view_id from mysql_innodb_cluster_metadata.v2_ar_members where CAST(member_id AS char ascii) = CAST(@@server_uuid AS char ascii)": Lost connection to MySQL server during query (2013)
#

In the database, I can see:

Aborted connection 5216418 to db: 'unconnected' user: 'myuser' host: 'vm43a' (Got an error reading communication packets)

The user myuser can connect remotely with mysql> without issue and the query is ok

What could be the cause please ? Thank you
