I just discover the tool workflow for vapi assistant. But when I configure a workflow for my assistant and I lunch the "talk to an assistant" it work just for the opening message. Once I answer the call finished with the error "room denied" Can you help me please ? Thanks

## Troubleshooting the "Room Denied" Error Check your assistant's configuration in the Vapi Dashboard, particularly: 1. Verify the server URL is correctly configured and accessible from outside your network 2. Ensure your webhook endpoint is properly set up to receive POST requests 3. Check your server logs for any errors preventing the webhook from being called If the issue persists, contact Vapi support with your call ID and timestamp of when the error occurred.

This occurs due to unmet conditions in the workflow, review the workflow’s conditions, ensure correct assistant configuration..
