I've just been affected by this on a Debian 8 install too. It seems the issue is related to the version of PHP > 5.6 which now checks SSL certificates are valid by default - if the CN of the certificate doesn't match the connection string used by Roundcube, the connection will fail.
Setting the Roundcube config default host connection string

$config['default_host'] = 'ssl://hostname';

so that hostname matches the CN in the SSL certificate solves the problem.
