以前正常使用的GataGrip,突然在某天报下面的错误提示:08S01
[08S01] Communications link failure The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server. No appropriate protocol (protocol is disabled or cipher suites are inappropriate).
从提示的英文能看出来,是 protocol的问题,打开数据库连接设置:
将useSsl设置为false,完美解决。
