I've problmes using this forum with https. My Firefox is configured to ignore ciphers with RC4 and that seems to be the problem...
"ssl_error_no_cypher_overlap" is the error I've got.
Taking a look into about:config reveals that camellia seems to be default off. Setting it true makes this site working again.
sslscan shows the supported ciphers:
Supported Server Cipher(s):
Accepted TLSv1 256 bits CAMELLIA256-SHA
Accepted TLSv1 128 bits CAMELLIA128-SHA
Accepted TLSv1 128 bits ECDHE-RSA-RC4-SHA
Accepted TLSv1 128 bits RC4-SHA
Prefered Server Cipher(s):
TLSv1 128 bits ECDHE-RSA-RC4-SHA
Short for all firefox-users: disable RC4(!!) and switch to Camellia
Question for the staff: RC4 because of old browsers?
