Hi All,

I seem to have run into an SSL/TLS issue that appears to have been introduced in 0.37.0 maybe from this? #458

My environment is as follows.

When including MySqlConnector >= 0.37.0 I receive the following exception:
The specified value is not valid in the 'SslProtocolType' enumeration..

Rolling back to 0.36.0 resolves the issue.

I'm not actually 100% sure why this is happening. From the reading I've done I believe AWS RDS is using the standard mysql tls with a valid public certificate.
As this is mysql 5.6.10 and based on https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/CHAP_MySQL.html#MySQL.Concepts.SSLSupport I would suspect that this is using the yaSSL over the Openssl they are using in newer versions.

I'm 100% happy to provide additional traces / information that might help narrow down the cause! Can log an aws support job if additional info is needed on that side.

Full exception:

The tests are supposed to verify compatibility with .NET Core 1.1 and SSL; that must not be working as intended:

MySqlConnector/.travis.yml

Line 39 in 9c450ed

- echo 'Executing netcoreapp1.1.2 tests with No Compression, SSL' && ../../.ci/use-config.sh config.ssl.json 172.17.0.1 3307 $NAME $OMIT_FEATURES && time dotnet xunit -c Release -f netcoreapp1.1.2
