I have been following the facebook bot setup guide and have setup a callback url that is running on an EC2 instance.

I am getting an error (see title of this) when trying to validate the callback url and verify token.

https://360.finance:1337/webhook is my webhook and the verify token is the same in my environment variable and in my facebook setting.

I set up SSL using LetsEncrypt and from what I can tell, the SSL is not showing as self signed so it looks to be working correctly (please note I'm new to all of this)

Checked at https://www.ssllabs.com/ssltest/analyze.html?d=360.finance&hideResults=on and all looks correct.

I have also included the facebook page token as an environment variable and included in my index.js file

I have tested netcat / telnet into that port on my ec2 ip and it is succeeding

We need to update the following on Facebook app settings page before adding The Callback URL or Verify Token.

  1. Privacy Policy URL
  2. Category
  3. App Icon (1024*1024)

Its weird that facebook doesn't point our exact error.

You must return an http response of the hub.challenge token as a plain text.

check you callback server, if it is running or not ?

the callback and token comes from your server.
