Incorrect TLS version in error message

[neonbunny]

If a specific TLS version is specified on the command line, e.g. --tls12, and that version of TLS is not supported by the server, an error message is displayed which reads Failed to connect to get certificate. Most likley cause is server not supporting TLSv1.0, try manually specifying version. However, it may not be TLS v1.0 that was selected at the command line.

The error message should include the version of TLS that was used, rather than the hard-coded value of "1.0".
