    @ELEMENTICY QMYSQL is not listed as available. I guess you will have to build it by yourself. https://doc.qt.io/qt-5/sql-driver.html
    But before that do this: set QT_DEBUG_PLUGINS environment variable to 1 before starting your app and then post its output here.

        Hi,

        The plugin is currently not pre-built anymore as Oracle changed their licensing with regards to MySQL so you'll have to build it yourself.

                @ELEMENTICY said in MySQL Connection failed,but i entered correct info of server:

                Can you teach me or explain it to me please?Thank you

                Go to @jsulm's link again and scroll down. There is a section called "How to Build the QMYSQL Plugin on Windows" -- it contains instructions on how to build the DLL.

                      You need to provide details of what you tried and what errors you got. Without the details, we can't help you.
