The issue occurs because ngrok can connect to your local machine trough the tunnel, but can’t access your local service (n8n).

Is your n8n instance accessible from your local machine?
Can you share your docker config? Are you using docker compose to run ngrok as a sidecar container?

We would need more information about your local setup to help out properly.

Hi @Kuti01 Personally i prefer NPM version of n8n if you are using any tunneling process for seamless integration and very basic setup, although it seems like your service i mean n8n is not reaching the ngrok, i think the most common cause here can be that you have not started the tunnel in the right localhost url, like your command for Ngrok server before n8n docker should be:

ngrok http 5678

And so once you have the server running now start that docker container and in the configs i recommend setting up webhook_url as the url you will get from the ngrok client and then after this save the config and start your setup and that should make everything working.

pspsps… If you are just getting started i really recommend trying NPM version of n8n (i personally used that) and it is very easy to setup as docker requires some configs before fully running.
