Hi @amn41 thanks for still helping me out.

When I run the command “ **rasa run --debug** ”. I am getting this log [another\_log.txt](https://forum.rasa.com/uploads/short-url/tXPrsmYtOJFxQz9QkEPAGEnSPd9.txt) (2.3 KB)

I have did nginx conf on my server. [nginx\_conf.txt](https://forum.rasa.com/uploads/short-url/1GujQTwchi1x4xiXjPjbsfUyROj.txt) (640 Bytes) for redirect the URL call to rasa.

I have run this command “ **rasa run -m models --enable-api --endpoints endpoints.yml --credentials credentials.yml -p 5005 -v --debug --log-file coursebotl\_logs --cors ‘\*’** ” and got this log file [coursebotl\_logs.txt](https://forum.rasa.com/uploads/short-url/oofvhvKS6nW1CwDWUEdiT8sRW8r.txt) (3.0 KB)

Now when I hit the URL “**[https://codomain.domain.in/webhooks/facebook/webhook](https://codomain.domain.in/webhooks/facebook/webhook)**” in browser I am getting “ **failure, invalid token** ”.

On rasa side I am getting “ **2021-03-15 14:21:40 WARNING rasa.core.channels.facebook - Invalid fb verify token! Make sure this matches your webhook settings on the facebook app.** ”

Even I am not able to test the CURL command because CURL command is showing “ **Connection time out** ”.

I don’t know where I am wrong.
