check_http is fail on all my web servers with SSLv3 disabled:

# ./check_http -H XXXX --ssl=1
CRITICAL - Cannot make SSL connection.
140362919835328:error:14094410:SSL routines:SSL3_READ_BYTES:sslv3 alert handshake failure:s3_pkt.cSSL alert number 40

From output above, it looks like it's still trying sslv3 even though I'm trying to force TLSv1. Am I reading that correctly?

Here's output from nmap showing the ciphers allowed on the webserver:

# nmap --script ssl-enum-ciphers -p 443 XXXX

Any help would be much appreciated.

Thank you.
