Do webhooks expire?

I have a photon that fetches weather data every 5 minutes. I have noticed that after a while either the webhook is not working or my photon stops calling for data giving me an indicator that it has not seen data for over 15 minutes (3 blinks on D7). If I reload the webhook and cycle power on the photon it seems to start fetching again.

This may be a dumb question (I am still very new to this) but does the computer that generates/publishes the webhook using the cmd prompt does not need to be online?

Thanks.

@mikewheels, webhooks will expire but only after a long time of not being used. However, if the webhook is generating errors from the target site, the webhook will be disabled. Take a look here:
