After you upgrade to Mac OS X 10.10.3 and try to connect to or refresh a Google Analytics or Google BigQuery data source, the following error might occur:
Internet communication error: Peer certificate cannot be authenticated with given CA certificates

Or, when you try to connect to or refresh a Google Analytics or Google BigQuery data source that is published to Tableau Server, the following error might occur:
Unexpected Error
Cannot connect to Tableau Server. Please check the server name and port and try again.
The issuer certificate of a locally looked up certificate could not be found
The root CA certificate is not trusted for this purpose



  • Tableau Desktop 8.2 and later versions
  • OS X Yosemite 10.10.3
  • Google Analytics
  • Google BigQuery


Option 1: Upgrade to Tableau Desktop 8.2.11, 8.3.6, or 9.0.2 and later versions

Option 2: (workaround) Download the Equifax Secure Certificate Authority

Contact your IT team or follow these steps:
  1. Close Tableau Desktop. 
  2. Download the Root 1 - Equifax Secure Certificate Authority certificate. For more information, see the resolution in InfoWorld: Yosemite 10.10.3 breaks some applications and HTTPS sites
  3. Open Tableau Desktop and try to connect to Google Analytics or BigQuery. 


Mac OS X 10.10.3 upgrade removed the Equifax Security Certificate Authority from the trusted system root store. The Equifax Security Certificate Authority signs GeoTrust, which is used by Google Analytics and BigQuery.
