Hi Ian, the message indicates that client and server could not agree on a cipher to use, as the ciphers supported/offered do not overlap.
Have a look at the server configuration, and which ciphers are supported. It might be something like SSLv3-only (no TLS), which is disabled by Mozilla components by now (is it already?). SSL-Labs might be helpful for debugging this: https://www.ssllabs.com/ssltest/ Regards, Jens On 09.12.2014 05:16, Ian Smithers wrote: > Hi all, > > I am using Thunderbird and the Sogo Connector to sync contacts with my > Carddav server.
