There could be several reasons for the error "com.intellij.execution.ExecutionException" when attempting to connect MySQL DB in DataGrip/PhpStorm, including:
Incorrect credentials: Make sure that you have entered the correct username and password for your MySQL database.
Firewall or network issues: Check if your firewall or network is blocking the connection to the MySQL database. You can try pinging the database and checking if you get a response.
MySQL server is not running: Check if the MySQL server is running on the host machine. If it is not running, you will not be able to connect.
Outdated JDBC driver: Make sure that you are using the latest version of the JDBC driver. You can download the latest driver from the MySQL website.
Invalid database URL: Check if the database URL that you are using is correct. The format of the URL should be something like "jdbc:mysql://hostname:port/database."
Insufficient permissions: Make sure that the user you are using to connect to the MySQL database has sufficient permissions to access the database.
