    Default A network service error has occurred (zclient/io).

    Hey World.
    Well I am asked to have a look at a Zimbra server that is not allowing people to login to the web interface.

    While trying to login to the web interface I get the following message with a nice big red icon above the login boxes.
    A network service error has occurred (zclient/io).

    Done a couple /etc/init.d/zimbra restart and cleared browser cache a few times. :-)

    Log files produce nothing of interest.
    View html source on the login page reviles the following java message:
