    Oops! Something went wrong on the server. If the problem persists contact the administrator.

  2. When performing a rebuild of the Coveo indexes via the Indexing Manager of Sitecore (Sitecore start menu > Control Panel > Indexing Manager), you may get an error dialog displaying the message: There was no endpoint listening at {WrongUrl} that could accept the message:

Causes

  1. The Coveo Admin Service may not be installed.
  2. The Coveo Admin Service may not be started.
  3. The Coveo Admin Service endpoint may not be configured correctly in the Coveo.SearchProvider.config file.
  4. The Coveo Enterprise Search 7 service may not be started.

Resolution

  1. Make sure that the Coveo Admin Service is installed (Administrative Tools > Services > Coveo Admin Service). 

    To install it, see Installing Coveo Enterprise Search (CES) On-Premises.

  2. Make sure that the Coveo Admin Service is started (Administrative Tools > Services > Coveo Admin Service).
  3. Make sure that the adminServiceUri property is valid:
    1. Open the Coveo.SearchProvider.Custom.config file (typically located under C:\inetpub\wwwroot\SitecoreInstanceName\Website\App\_Config\Include\Coveo).
    2. Locate the defaultIndexConfiguration/adminServiceConfiguration/adminServiceUri node.
    3. Enter the endpoint of the Coveo Admin Service (typically http://localhost:80/AdminService).
  4. Make sure that the Coveo Enterprise Search 7 service is started (Administrative Tools > Services > Coveo Enterprise Search 7).
