      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..

      at IM.Admin.Controllers.TestController.getUser() in /home/jenkins/agent/workspace/Dev-YallaChat-NetCore-Admin-Build/IM.Admin/Controllers/TestController.cs:line 29

      执行SQL错误:English Message : Connection open error . Authentication to host '192.168.1.x' for user 'ht_v1' using method 'mysql_native_password' failed with message: Bad handshake
      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 to host '192.168.1.x' for user 'ht_v1' using method 'mysql_native_password' failed with message: Bad handshake. | select ui.user_id,ui.user_name,ui.id from iden_account ia
      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
