I am getting an error when trying to connect to a server while using TLS:
SSL handshake failed: EOF occurred in violation of protocol (_ssl.c:590)

On the server side I am getting:
warn: Driver connection TLS handshake failed: 336027900 - error:140760FC:SSL routines:SSL23_GET_CLIENT_HELLO:unknown protocol

This is coming up while working on #4815, so there could be something I am doing there, but some tests from the next driver seem to exclude this.
