Hi @Mariano 

Jira 10.x requires the MySQL 8.x JDBC driver (mysql-connector-java-8.x.x.jar). Ensure you downloaded a compatible version with MySQL 8.x and Java.

Here is the download URL: https://dev.mysql.com/downloads/connector/j/

Download and copy the .jar file (e.g., mysql-connector-java-8.0.xx.jar) to your Jira installation's lib folder (<JIRA_INSTALL_DIR>/lib)
