Socket.io disconnecting on Ngrok & local

Rasa Open Source
1

The rasa webchat integration was working fine from the past 18 days. Now after restarting the server, the socket.io started disconnecting on the ngrok server and local too.

rasa run -m models --enable-api --cors “*” --debug

Error on local server

Error with Ngrok

Hey @anuragchaudhary, would you mind sharing your credentials.yml file? (Omitting any sensitive data, of course).

What happens if you restart the ngrok server?

the contents of credentials.yml are as follows

rest:

socketio:
  user_message_evt: user_uttered
  bot_message_evt: bot_uttered
  session_persistence: true

I couldn’t see any problem with ngrok server
