kettle的版本是9.4的。用的驱动是8.0.33.mysql版本是8.0.28.本地能连接上。但是线上远程就报错Connection failed. Verify all connection parameters and confirm that the appropriate driver is installed.Communications link failureThe last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.这个应该怎么解决呢 ?有没有大佬远程支援一下的。搞了好几个小时呢。要崩溃呢
