Symptoms

You have installed Sitecore SXA and have an issue opening the Coveo Diagnostic Page.

Cause

There’s an issue with the way the coveo_website site is resolved in SXA.

Resolution

This issue was fixed in the February 15, 2023 release.

Workaround

Open <SITECORE_INSTANCE_ROOT>\App_Config\Modules\Coveo\Coveo.Authentication.config in a text editor.
Locate the <federatedAuthentication> element.

Just above the <federatedAuthentication> element, add the following block.

<!-- SXA handles site resolving differently. With this added setting, the coveo_website will be properly resolved when needed. -->
<experienceAccelerator>
  <siteResolving>
    <site name="coveo_website" resolve="before" />
  </siteResolving>
</experienceAccelerator>

The beginning of the file should now be as follows:

<!--
    Do not modify this configuration file.
    Instead, you should patch this file using a Coveo.Authentication.Custom.config file.
-->
<configuration xmlns:patch="http://www.sitecore.net/xmlconfig/" xmlns:role="http://www.sitecore.net/xmlconfig/role/" xmlns:set="http://www.sitecore.net/xmlconfig/set/">
  <sitecore role:require="Standalone or ContentDelivery or ContentManagement">
    <!-- SXA handles site resolving differently. With this added setting, the coveo_website will be properly resolved when needed. -->
    <experienceAccelerator>
      <siteResolving>
        <site name="coveo_website" resolve="before" />
      </siteResolving>
    </experienceAccelerator>
    <federatedAuthentication type="Sitecore.Owin.Authentication.Configuration.FederatedAuthenticationConfiguration, Sitecore.Owin.Authentication">
