Java: com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: Could not create connection to database server [duplicate]

Answer 1

In my case, I was using Maven Dependency to use JDBC connector. I just changed the version of dependency. This worked for me

    
        mysql
        mysql-connector-java
        5.1.46
    

Add the below version and you will be fine:

8.0.20
