I tried to use different version of webchat 0.4.1, 0.5.3, 0.5.9 still doesn’t work.

Rasa logs:

```auto
2019-06-25 12:17:11 INFO engineio.server - e15fd17ab7fc42a992207534a125be05: Sending packet OPEN data {'sid': 'e15fd17ab7fc42a992207534a125be05', 'upgrades': ['websocket'], 'pingTimeout': 60000, 'pingInterval': 25000}
2019-06-25 12:17:11 INFO engineio.server - e15fd17ab7fc42a992207534a125be05: Sending packet MESSAGE data 0

```

I’ve read many threads here and i think this is about upgrading websocket but i don’t know what doest i mean.

So i have flask hello world with rasa-webchat and running rasa in another shell.

Can you tell me please how i can fix this problem?

The error was caused by CORS. So i point ngrok url to webchat.

@SallemiDorsaf I had the same issue , I resolved it by updating to latest version of rasa. Once you have your bot ready add the below configuration in the credentials.yml file

```
socketio:
user_message_evt: user_uttered
bot_message_evt: bot_uttered
session_persistence: true

```

Now start your bot using this command 🙂

`rasa run -m models --enable-api --cors "*" --debug`
