when trying to scan hosts in maintenance mode I receive the following error in my logs and the scans fail

2017-12-20T12:55:04.962-07:00 [09568 error 'HttpConnectionPool-000000'] [ConnectComplete] Connect failed to <cs p:06888e98, TCP:1xx.xxx.xxx.xx:5489>; cnx: (null), error: class Vmacore::Ssl::SSLException(SSL Exception: error:14094410:SSL routines:SSL3_READ_BYTES:sslv3 alert handshake failure)

any suggestions
