IFTTT recipe failing with 'Trigger Timeout Error' but only for one of my devices

I have an IFTTT recipe which is triggered by an event published by a Photon, this recipe used to work just fine, but recently is has completely stopped, with the IFTTT log for the recipe just a long series of ‘Trigger Timeout Error’.

I can see the events from the device in Particle Console so they are being published correctly.

I have tried deleting and re-creating the IFTTT recipe but this made no difference.

Another IFTTT recipe I have which listens for an event for a different Photon device has continued to work correctly, so the problem seems somehow specific to the one device. Can anyone help?


Looks like this may have been caused by a faulty webhook, which I have now deleted. IFTTT recipe is now working again.
