  • can you please check whether the xconnect certificate details are correct in your Sitecore Instance. Also, the permission to xconnect certificate is added to your Sitecore Instance app pool.
    Check xconnect logs, thumbprint, windows service logs, xconnect thumbprint details in app_config and app settings file too.
