Hey folks, I'm a beginner and I'm having some issues with the first step of the training. Can you help?

Hey there!

Hamilton here.

I’m new to n8n and I’m a Product Designer. I’m doing the 2-hour training to learn how n8n works but I’m failing my first assignment as the system shows me an error message saying “The service refused connection - maybe it’s offline”. The exercise should be simple, just connecting a form trigger to a send an email action.

Here are some images of the error and the configuration I have on the email node.

Thanks in advance!

It looks like your topic is missing some important information. Could you provide the following if applicable.

  • n8n version:
  • Database (default: SQLite):
  • n8n EXECUTIONS_PROCESS setting (default: own, main):
  • Running n8n via (Docker, npm, n8n cloud, desktop app):
  • Operating system:

I’m using:

  • n8n cloud
  • windows 10

Your SMTP credentials likely aren’t configured correctly.

I would trouble shoot that and ensure that connection is working as expected


Hey Liam, thanks for the quick response. I was able to fix it and yes, it was the SMTP!
