New order emails stopped working

Suddenly our notification emails have stopped working. The email notification worked until Monday afternoon. 4/11 Was the last day that we received any notifications from woocommerce. Everything had been working perfectly for years prior.

I am able to manually send the notification emails through the dashboard but we rely on the emails to notify us of new orders.
