Push notifications from Prowl have stopped

I don’t know if this is a Vera Alerts problem but I have stopped receiving all notifications. I am on UI5, Vera 3 and have been using it in this configuration for several years with no problem with notifications. In the last day or so no notifications have come thru. I am using a Prowl profile and haven’t changed anything in the configuration on Vera Alerts or Prowl. EVen when I use thew “Send Alerts” tab nothing goes thru. Any ideas on what could be wrong?

There seems to be an issue with the Prowl Servers or the plug-in itself. Other users are reporting the same problem. See this thread: http://forum.micasaverde.com/index.php/topic,11520.345/topicseen.html
