My ovirt engine (physical) host died :(

  I'm having real trouble creating a new engine...
  The original database is on a remote host and is still up and runnning.
  I installed another engine and restored 'files':

  engine-backup --mode=restore --file=20160830.ovebak --log=/tmp/restore.log --restore-permissions --scope=files


  How ever when I connect to the UI it wither redirects to localhost.localdomain and fails

  Or I get

  java.security.cert.CertificateException: No name matching localhost.localdomain found

Any clues on what I need to fix, or do to deploy a new engine ?
