Aeotec Siren/doorbell notifications issue

Hi All,

Had question about the aeotec door bell/siren. I for some reason don't get any notification when my door bell is button is pushed any more. I had a rule set up in the notifications section that I'd doorbell button was pressed then it would ping our phones. I looked in the log and noticed there was an error. Can anyone tell me what it means.
