Hello everyone,
I am using mysql-connector-j 8.3.0 without any problems but when I tried to update the version to 8.4.0 or to 9.x I got a problem when start the application and trying to connect to the database.
Caused by: java.sql.SQLTransientConnectionException: HikariPool-default - Connection is not available, request timed out after 30004ms.
There are times when the connection does not cause any problems but it takes a long time to start. Do you know what could be the cause of this? With version 8.3.0 the connection starts very quickly.
