SSLHandshakeException и CertificateException при создании соединения SQL

0 голосов
/ 07 мая 2020

Я только начал изучать SQL и пытаться использовать JDB C создать соединение с mysql, но каждый раз, когда я пытаюсь установить соединение, появляется это сообщение об исключении. Я почти уверен, что написал правильный URL-адрес и могу открыть его в sqlyog, я не уверен, в чем проблема. Как мне решить эту проблему? 

Exception in thread "main" com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure

The last packet successfully received from the server was 1,457 milliseconds ago.  The last packet sent successfully to the server was 1,451 milliseconds ago.
