Error: Failed to receive response in Chat Webhooh

Hi Dears,

I’m just starting to use n8n and I’ve developed a flow that has a chart node. In the workflow’s internal chart, the outputs appear normally. But when I make the chat public and use the webhook, any question I ask returns the error ‘Error: Failed to receive response’. How can I fix this?

I’m using the n8n v1.113.3 executing on a EC2 Amazon-Linux cloud.

Thanks,

Roberto
