Hello! I would like know if you can help me with the following error:
It happened always when I try activate the node Trello Trigger.

Information on your n8n setup

  • n8n version: 0.215.1
  • Database you’re using (default: SQLite): I don’t know what is it
  • Running n8n with the execution process [own(default), main]:
  • Running n8n via [Docker, npm,, desktop app]: with server… I think is Docker

Hey @Paulo_Machado,

Can you check that the webhook url is not localhost, I suspect that is the issue.

You can change this by setting the WEBHOOK_URL environment variable to whatever domain you are using.

Thanks! I Will do It and then come back to talk If I got It. But, today my n8n is hosted on a server. Can you explain me a little more How do I do this check?

Above the credential that you select it will say webhook urls, if you click that it will show you what you are using.

Hello, Jon

At the moment the Webhook_URL is:

I’ve done test WEBHOOK_URL PRODUCTION but the error continues :confused:

The most string is when I’ve done test a node WEBHOOK, it’s works! But if I use the Trello Trigger the error happens.
