My server went offline for a day and now facebook has stopped sending requests to my webhook. This is the error message i get:
Your Webhooks subscription for callback URL https://myurl has not been accepting updates for the past 0 minutes. This subscription has been disabled. To reactivate, just make a POST request with the same parameters or visit the Webhooks tab in the app dashboard. Scopri di più about Webhooks.
What post request is he talking about? i went to webhooks tab but doesnt seem to have any effect. Anyone had this problem?
