Localhost error 404&408

[Madurba]

Hello commu!
I want to send data from a form (Tally) to a webhook node.
I am in localhost and have enabled workflow, enabled listening to the webhook node and started my n8n session with n8n start --tunnel.
No error on the n8n cloud server url which is generated well at startup.
However when I trigger the form submission, the webhook node doesn’t hear anything and the form after a delay goes to error 404 or 408 sometimes.

n8n version 0.212.1
npm 8.13.1
node.js 18.4
MacOS 12.5.1

Do you think this is a problem on the n8n cloud server side?
Thanks in advance for those who have already had this problem !

Hey @Madurba,

Welcome to the community

I suspect the issue could be that the tunnel url has changed, I would restart n8n and check if the new url works.

Hi ! Thank you.
I have already regenerated the url by restarting several times without success…
I had read on a topic that sometimes it is the n8n cloud tunnel server that can bug.

Hey @Madurba,

It can indeed as the tunnel is not really designed for production environments, If you are hitting a 404 though it will be that the tunnel url has changed.

Looking at that screenshot it could be something odd with the brew version as well. Have you tried running from npm to see if that does anything else?

I finally managed to launch a working tunnel through a Docker run with this command line :

docker run -it --rm \
	--name n8n \
	-p 5678:5678 \
	-v ~/.n8n:/home/node/.n8n \
	n8nio/n8n \
	n8n start --tunnel

Thanks a lot for your help !
