Opening Sitecore Indexing Manager Returns a 405 (Method Not Allowed) Error


In Sitecore, you get a 405 (Method Not Allowed) error when trying to connect to one of the following:

  • the Sitecore Indexing Manager
  • the Coveo for Sitecore Diagnostic Page (Control Panel > Coveo > Diagnostic Page)


  • Coveo for Sitecore 863+
  • Troubleshooting
  • Admin Service, Indexing Manager, Diagnostic Page


There are two possible causes and solutions.

The Admin Service Isn’t Running

Make sure the Coveo Admin Service is running.

The Admin Service Was Secured and Coveo for Sitecore Was Not Configured Accordingly

It’s possible that the Admin Service was secured but Coveo for Sitecore was not configured accordingly. Therefore, the first thing to check is if the Admin Service is secured:

  1. On your CES Server, connect to this address http://localhost/adminservice?wsdl .
    1. If you can connect to the page, it means your Admin Service is NOT secured.
    2. If you can’t connect to the page, try connecting to https://localhost/adminservice?wsdl. Successfully connecting to that page means the Admin Service is secured.
  2. If your Admin Service is secured, configure Coveo for Sitecore accordingly (see Securing the Admin Service).
