    Catch additional connect fail cases.

    When fixing bug/1195910, some other failure
    cases weren't considered (ie not authorized,
    unreachable dest etc).

    We should fix this up to handle the various
    connection error states accordingly and also
    add some hints to the log output to help
    determine where to look in case of failure.

    Fixes bug: 1201592
