SAP Data Services Error - ETL / API job Failing


We have a daily API job that runs SAP Data Services. It has been running successfully for months. Today it failed with an error: "Could not create a new session (Adapter: 'SalesForce_Adapter').>."

Digging deeper into the error log we have:

"8/27/15 9:18:40 AM Fault-tolerance-login-failed : There was a communication error when talking to Connection has been shutdown: PKIX path building failed: unable to find valid certification path to requested target
8/27/15 9:18:40 AM Retry : 2. Waiting 15 mins before trying to login to again."

Has anything changed on Salesforce side that would cause this?

Hi George, 

It was a result of Salesforce moving from the SHA-1 to SHA-256 certs. We needed to install the certs on the machine that runs Data Services and then everything was fine.
