Configuring Sitecore 9.0.2 on scaled environment. On the CM environment when we click any of the items related to our website, we see the exception below. Whereas all the Sitecore ootb items in content tree are not throwing this exception. If this is related to xConnect, we verified that all the xConnect URL are accessible from CM with no issues and we are using exact same certificates in the connection string on CM.

enter image description here

We see the following exception in Sitecore logs:

FATAL [Experience Analytics]: Failed to synchronize segments. Message: Ensure definition type did not complete successfully. StatusCode: 401, ReasonPhrase: 'Invalid certificate', Version: 1.1, Content: System.Net.Http.StreamContent, Headers:

Can someone please suggest what this error is all about?

  • Can you please check that Analytics are loading or not in dashboard landing page and experience analytics option? – Amit Kumar Feb 22 at 19:57
  • Thanks for you response Amit. No we see error messages on Experience Analytics dashboard. Where as in logs we see multiple exceptions for Message: The certificate was not found. Source: Sitecore.Xdb.Common.Web. – Rathan M Feb 22 at 20:18
  • It means browser console will also show JavaScript error, if analytics not loading. Can you please follow the article medium.com/@sivalingaamorthy/…. kamsar.net/index.php/2017/10/All-about-xConnect-Security to install xConnect certificate properly – Amit Kumar Feb 23 at 5:09
  • We observed this is happening only when we are set the role:define as "ContentManagement, Processing, Reporting" in web.config. Because we are using same instance for all these three roles. Whereas if we just use "ContentManagement" this works fine. If we want to use the same IIS Instance for all the three Roles, our understanding is setting the "Role:Define" is all we need to do. Any thoughts?. – Rathan M Feb 25 at 21:53
  • As per official doc doc.sitecore.com/developers/91/… it's correct. Try to add CM,IS and xConnect on same server and rest on other server. – Amit Kumar Feb 27 at 3:11
