Having problems making TLS connections to an instance of apache.
The server version is:
Apache/2.2.22 (Unix) mod_ssl/2.2.22 OpenSSL/0.9.8t
The ssl config includes:
SSLProtocol TLSv1 SSLv3
SSLCipherSuite RC4-SHA:AES256-SHA:ALL:!ADH:!MD5:!EXP:!LOW:!NULL
SSLHonorCipherOrder on

#SSLInsecureRenegotiation on
If I try and connect using Firefox with only TLS enabled, the
connection fails (get the message 'The connection to the server was
reset while the page was loading'). With SSLv3 enabled in Firefox, the
connection works fine.
Trying using openssl command line:
openssl s_client -connect 127.0.0.1:443 -tls1
gets
CONNECTED(00000003)

Any clues as to why the TLS connection is not working - is there some
config value I am missing or have wrong?
What version of SSL are you using? There was a problem with the update
of "openssl-1.0.1a" that caused problems with Postfix with certain
domains.
Try this for starters:
openssl s_client -connect 127.0.0.1:443 -tls1_2
openssl s_client -connect 127.0.0.1:443 -tls1_1
openssl s_client -connect 127.0.0.1:443 -tls1
openssl s_client -connect 127.0.0.1:443 -ssl3
Post the connect or fail results back here.
Command line openssl version is:
OpenSSL 0.9.8t 18 Jan 2012 (Library: OpenSSL 0.9.8k 25 Mar 2009)
-tls1_1 and -tls1_2 are not recognised options
-tls1 fails
-ssl3 connects fine.
The apache httpd has been compiled against the same openssl (and is
running on the same box, ubuntu 10.04 LTS)
Apache/2.2.22 (Unix) mod_ssl/2.2.22 OpenSSL/0.9.8t
I've tried re-compiling Apache with OpenSSL 1.0.1a and now get the
following results when using the command line to check (with -tls1 as
the option)
/usr/local/ssl/bin/openssl s_client -connect 127.0.0.1:443 -tls1 -state -msg

TLS session ticket:
That's more than I got with the older OpenSSL, but it still seems to
indicate a problem. I also still get the same response (unable to
connect) when trying Firefox.
The server build now reports: Server Version: Apache/2.2.22 (Unix)
mod_ssl/2.2.22 OpenSSL/1.0.1a
OpenSSL command line says: OpenSSL 1.0.1a 19 Apr 2012
If I try the openssl command line now with -tls1_1 or -tls1_2 it
connects with no errors, as does ssl3
It's only -tls1 that seems to have the problem - but that is enough to
stop firefox (and other tls1 only clients) from connecting.
Odd that tls1.1 and tls1.2 work, but not just tls1
