I don't think the second error is related to Coveo.

  • Does your CES, Search API and Coveo for Sitecore versions are matching (same release month)?
  • Is your <SearchApiUri> element value correct in your Coveo.SearchProvider.Rest.config file?
  • Is your <ApplicationSecret> element value correct in your Coveo.SearchProvider.Rest.config file?
  • Is your <RestEndpointPath> element value correct in your Coveo.SearchProvider.Rest.config file? It should be /coveo/rest.

Thanks, I have checked every thing you mentioned Coveo.SearchProvider.Rest.config, they all were correct. While doing this checks I noticed config.yml in the Coveo API install folder was missing paths to certificates. Once I fixed the certificate paths the Rest End Point error did go away.

I still get 500 internal error on "Coveo Security Service".

Coveo Security Service is the webservice installed by Coveo for Sitecore inside Sitecore to expand Sitecore role members at indexing time. It is meant to be called by the CES Security Provider with the Sitecore credentials defined in the Coveo.SearchProvider.config file <SitecoreUsername> and <SitecorePassword> elements.

I think your configured credentials are invalid. You can update them from the Sitecore Control Panel (see Configuring the Sitecore Credentials).

Might help someone, I've recently ran into the same issue and everything checks out in the configs, etc. The solution to my issue was to change the Coveo Search API service login account to a domain service account with full control on the CES folders.
