The options flag is spelled options= with an s

I don't think you want to disable SSLv3 as well, so just use
options=NO_SSLv2

Most likely the client is senting a SSLv2 hello message, not SSLv3/TLS.
All known browsers do this unless manually configured otherwise. This in
order to keep compatibility with SSLv2 servers, then upgrading the
connection to SSLv3/TLS after the initial handshake if the server
indicates it supports upgrading..

So you should use the options=NO_SSLv2 flag. The version= flag is only
for very controlled environments where you have control over the
clients. In this mode both SSLv2,3 & TLS hello messages is accepted, but
if a SSLv2 hello message is used the connection must be upgraded to
SSLv3/TLS before the request is accepted.

If version=X is used then only that exact version of SSL/TLS is
understood, and the hello message sent by the client must be of the
correct version.
