Environment: Sitecore 9.0.2 + SXA in XP0 on VM

What I am trying: I am trying to enable xConnect on my VM.

What I did: I followed the steps provided in this blog but was unable to get it up.

Log: Under xConnect, I have no log corresponding to it. Under my Sitecore Client, I have the following log entry:

Exception: System.InvalidOperationException
Message: The certificate was not found.
Source: Sitecore.Xdb.Common.Web
   at Sitecore.Xdb.Common.Web.CertificateWebRequestHandlerModifier.Process(HttpClientHandler handler)

What are my findings till now: I have validated my settings and have the following points in order:

  1. thumbprint of certificate in the certificate manager and both the configs of xConnect
  2. The certificate is not expired.
  3. On browsing the xConnect site with https, I do not see any warning or error.

Where should I look further? Regards

I wrote about this troubleshoot a few weeks ago, but here are the main steps:

1. Make sure you have the rights certificates on the right places:

Local Computer Certificates

  • Trusted Root Certification Authorities:

DO_NOT_TRUST_SitecoreRootCert with private key

  • Personal:

One certificate for your xConnect website issued by DO_NOT_TRUST_SitecoreRootCert

Current User Certificates

  • Trusted Root Certification Authorities:

DO_NOT_TRUST_SitecoreRootCert with private key

  • Personal:

DO_NOT_TRUST_SitecoreRootCert with private key

2. Make sure you have the right xConnect certificate thumbprint here:

  • .sc\App_Config\ConnectionStrings.config
  • .xconnect\App_Config\AppSettings.config
  • .xconnect\App_Data\jobs\continuous\AutomationEngine\App_Config\ConnectionStrings.config
  • .xconnect\App_Data\jobs\continuous\ProcessingEngine\App_Config\ConnectionStrings.config

3. Make sure you have the right certificate on IIS for xConnect website

4. Make sure the xConnect website ISS App user has the right access on your certificate

  • I was not able to find .xconnect\App_Data\jobs\continuous\ProcessingEngine\App_Config\ConnectionString.config. I am on Sitecore Sitecore.NET 9.0.2 (rev. 180604). What I have is IndexWorker and its AppSetting.config or ConnectionString.config does not have a Thumbprint.

  • @Renuka in case of scaled environment path can be different. If processing is set as independent node the path would be .processingEngine\App_Data\jobs\continous\ProcessingEngine\AppConfig\ConnectionStrings.config Where .processingEngine is directory where that node is stored.

Check the client certificate thumbprint mentioned in the ConnectionStrings.config is installed in the web server
