[Errno 111] [SSL: SSLV3_ALERT_HANDSHAKE_FAILURE] sslv3 alert handshake failure (_ssl.c:727)

I am using the SABnzbd container and all of the connections have the following error if i tick SSL:

[Errno 111] [SSL: SSLV3_ALERT_HANDSHAKE_FAILURE] sslv3 alert handshake failure (_ssl.c:727)

I have searched, but can't find anything directly linked to SABnzbd

Many thanks in advance.,
