    Hi @njhelloworld,

     

    If you can open the MySQL port with the browser, it's not a MySQL connection but a Web connection, e.g., you are configuring https://127.0.0.1:8080/ instead of mysql://root:password@127.0.0.1:3306/database?encoding=utf-8. If that is the case, I would double check the MySQL connection settings, as MySQL is not HTTP.

     

    All the best,

    Hi,

     

    this is a MySQL error message. It is coming from the JDBC driver so that part of the setup is correct.

    However, the connection information (host name, port) is probably not right.

     

    Regards,

    T_T ..the hostname with port can be opened in the browser without rapidminer, I guess the hostname and port are working properly
