Unable to Connect: invalid packet: scramble_length(0) != length of scramble(21) in msf6 auxiliary(scanner/mysql/mysql_login)

I am getting the following error when trying to run the mysql_login auxiliary module in msf6:

Unable to Connect: invalid packet: scramble_length(0) != length of scramble(21)

I have checked the following:

  • The host, port, username, and password are correct.
  • The MySQL server is running.
  • The firewall is not blocking access to the MySQL server.
  • I have tried restarting the MySQL server.
  • I am using the latest version of msf6.
  • The version of msf6 is compatible with the version of the MySQL server.
  • I have checked the MySQL server logs for errors.
