My workflows are terminating at that point in the workflow and giving “Exception: The request was aborted: Could not create SSL/TLS secure channel.” as an error. It was working up until some time in the last couple months. Nothing has been changed in the workflow and nothing has been changed in the list other than adding some additional columns.
The account calling the workflows still has full access and works properly.
Starting 2010 workflows works properly which makes me think it’s a problem with the 2013 command or it’s interaction with Sharepoint. Here is a screenshot of the settings of the workflow. I’ve removed the workflow user credentials that would normally be there.
