SSL connection to a non-secure port

If you have weird SSL errors and this one appears, you are trying to speak SSL to a daemon that doesn't understand it:

$ openssl s_client -connect 222.222.222.222:443
CONNECTED(00000003)
5057:error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol:s23_clnt.c:567:

If you get this with Apache, be sure that you have SSLEngine On in the applicable VirtualHost and be sure that mod_ssl is being loaded.
