Cannot connect facebook messenger webhook

I’m running a rasa assistant on localhost with ngork configured and then attempted to connect it to facebook messenger, however, when I attempt to verify, I get an error.

FB verification request does come in but there is not endpoint available that will respond to it? What could be the cause?

Did you pass the correct “verify” token to facebook (same one you have in credentials)?

Yes, I rechecked the credentials and they are okay. From the 404 we can infer that the request from facebook comes through but there is no service running on the path /webhooks/facebook/webhook to serve that request.

One thing- Facebook requires https to connect to. Did you specify the https or http address?
