    Description

      When the .net programs are directly connected to the mysql database, all are normal, and there is no error reported for 1 million pressure tests, but the following errors are occasionally reported when connecting through maxscale:
      SqlSugar.SqlSugarException: English Message : Connection open error . Authentication method '' not supported by any of the available plugins.
      Chinese Message : 连接数据库过程中发生错误,检查服务器是否正常连接字符串是否正确,实在找不到原因请先Google错误信息:Authentication method '' not supported by any of the available plugins..

      left join user_info as ui on ia.id = ui.user_id |

      The mysql user account uses the standard authentication method:mysql_native_password

      Not sure of the cause of the problem, please help
