Using the MySQL 0.4.13 connector I can successfully create and connect to my source, but switching to a 0.5+ connector version I get this error :

Hi <@U0305L9MKGQ>, this topic might help you: <https://discuss.airbyte.io/t/source-mysql-poolableconnectionfactory-error/244>
We suggest to set `enabledTLSProtocols=TLSv1.2` in the JDBC extra parameters

<@U02UC3T12PJ> Yes I tried this but IT would not work. I would get a `The server selected protocol version TLS10 is not accepted by client preferences` error in that case.

`enabledTLSProtocols=TLSv1.0` instead but I would then get a `No appropriate protocol (protocol is disabled or cipher suites are inappropriate)`error.

Ok I fixed the issue by setting the `verifyServerCertificate` &amp; `useSSL` JDBC params to false and succeeded upgrading to version 0.5.6.
