    After migrating to Aleph 23 the OPAC is unavailable "Service temporarily unavailable"

    • Product: Aleph
    • Product Version: 23
    • Relevant for Installation Type: Dedicated-Direct, Direct, Local, Total Care



    We have completed all the steps in the Upgrade Express utility, however, the online catalog is now unavailable. We are getting the error message in the browser:



    "Service Temporarily Unavailable"

    The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later."



    Both apache and www_server are running, but they don't appear to be talking to one another.


    I've re-checked all the configuration files I could think of, and everything looks okay.

    Apache is running at port 8991 and www_server is running at 4991.

    In the log apache, I have only this line: - [22/Jun/2016:14:50:55 +0200] "GET /F HTTP/1.1" 503 323



    Service iptables was activated.


    Disable IPtables on the servers to get Aleph working.


    as root user --> service iptables stop

    The IPtables were only deactivated temporarily. Please disable IPtables permanently, so that they will not start again if the server reboots.


    Additional Information

    Please note it's an Exlibris requirements that IPtables will be off on the server.
