Probable solution/findings to verify:

1. Generally occurs with send email functionality in workflow.
2. Check outgoing email settings for the farm are correct.
3. Disabled firewall on the Exchange/SMTP server.
4. Check App management service is running, UPA is set up and  completed sync such that the user running the workflow has a profile.
