Hi team,
My chatbot is not working suddenly from past 20 days, for each activity directline api is responding with 504 error (Failed to send activity: bot timed out). We have not done any change. Checked API key expiry date also but all keys are valid. Please let me know how to resolve this.
Thanks!
