Hi, I have installed Rasa X on Google Cloud Compute Engine using docker. I have configured SSL certificates and assigned domain name. So now I have URL like this https://domain_name.com/ When I open it in UI, everything is working (including custom actions). However, it doesn’t work, if I specify the same URL in Webhooks Callback URL for integration with Facebook Messenger. I have the error: * The URL couldn't be validated. Response does not match challenge, expected value="1903563423", received="\u003C!doctype html>\u003Chtml..." I could see in docker logs: rasa-x_1 | [2019-08-06 17:40:27 +0000] - (sanic.access)[INFO][172.19.0.9:59052]: GET http://domain_name.com/webhooks/facebook/webhook?hub.mode=subscribe&hub.challenge=729904826&hub.verify_token=token 200 3082 nginx_1 | 66.220.149.18 - - [06/Aug/2019:17:40:27 +0000] "GET /webhooks/facebook/webhook?hub.mode=subscribe&hub.challenge=729904826&hub.verify_token=token HTTP/1.1" 200 1542 "-" "facebookplatform/1.0 (+http://developers.facebook.com)" nginx_1 | 2019/08/06 17:40:27 [info] 9#0: *191 client 66.220.149.18 closed keepalive connection

What Callback URL should be for integration with FB messenger?
