+###### Note
+
+TLS 1.2 for MySQL connections requires MySQL version 5.7.28 or higher. If your MySQL server enforces TLS 1.2 only (for example, `tls_version = TLSv1.2`) and the server version is below 5.7.28, the SSL handshake fails with a `Communications link failure` error. To resolve this, upgrade your MySQL or Aurora MySQL database to version 5.7.28 or higher.
