ssl_choose_client_version:unsupported protocol

That does suggest to me that the newest protocol version supported by the server is older than the oldest protocol permitted by the upgraded client. Given that your working client shows a negotiated TLSv1.1 that's probably the highest/newest supported by the server.

Update: check the MinProtocol setting in the openssl config of your upgraded machine. You may have to configure it downwards towards TLSv1.1 to permit the connection.
