Service Unavailable Error Following Essentials REST Install



  • Drew Millen
    That's very strange...  have you tried restarting IIS?    Here's the definition of a 503 error from the website:


    503 Service Unavailable

    The server is currently unable to handle the request due to a temporary overloading or maintenance of the server. The implication is that this is a temporary condition which will be alleviated after some delay. If known, the length of the delay MAY be indicated in a Retry-After header. If no Retry-After is given, the client SHOULD handle the response as it would for a 500 response.

    Note: The existence of the 503 status code does not imply that a server must use it when becoming overloaded. Some servers may wish to simply refuse the connection. <p> </p>

    The error was actually related to an install problem. You must install both the REST API and the WEB ADF apps at one time. If you have the Eseentials ADF installed and add on install just the REST portion, the application does not get correctly installed. M

    Thank you for the update.  It sounds like you have identified an issue with our current installer.  Our next upcoming release (2.3) includes a new installer which will prevent this issue from occurring again.   Thank you for your patience and I apologize for any trouble these installation headaches have caused.   Best regards,
