Hey all. After doing a lot of digging, it seems this is old an issue steming from the MySql version on the AWS server with old versions forcing SSL verification (yaSSL forcing SSL vs OpenSSL defaulting to server settings) -- I scheduled an update to the latest AWS Aurora version and it fixed the "unsupported protocol" error!
But now i'm getting:
error: SSL connection error: error:141A318A:SSL routines:tls_process_ske_dhe:dh key too small
This is due to a security response to the "Logjam" hack, where now DH keys are set to a certain size -- if you're connection does not have the same size key as the server, you get the error.
So I'm going to try and amend my .cnf config file to lower the security level:
CipherString = DEFAULT@SECLEVEL=1
I think OpenSSL defaults to level 1. Will let you know how it goes.
