-For BGP-enabled environments, this command might take a few moments to succeed while BGP routes are advertised and propagated through the network. The `mariadb-copy-data` pod needs to receive the route to the podified MariaDB IP address through BGP before it can establish a connection. If the command fails, wait a few seconds and retry. The connection should succeed once the BGP route advertisement is complete.
