The most common reason for seeing "SSL certificate verify failed" is that you are trying to connect to a server that is using an invalid certificate. You can try changing the SSL settings in the Options/Connect/Options/SSL dialog to "Display invalid certificates for approval" to see if that makes a difference.

The most common reason for seeing "SSL wrong version number" is that the server is using an SSL version that is no longer secure and should not be used. See here for a previous post relating to allowed ciphers.
