• Hello everyone,

  I’m having trouble connecting two workflows with a webhook on my new n8n installation.

  • n8n EXECUTIONS_PROCESS setting (default: own, main): main

  • Running n8n via (Docker, npm, n8n cloud, desktop app): Docker

  • Operating system: Windows

  The Problem

  I am getting a 404 “resource not found” error when trying to call a webhook using my host’s IP address (192.168.1.8).

  I have already tried:

  1. Creating a Windows Firewall rule to allow traffic on port 5678.

  2. Using my computer’s IP address (192.168.1.8) instead of localhost.

  3. Creating a minimal test case with two simple workflows (one sending, one receiving), which also failed with the same 404 error.

  Here is a screenshot of the simple test case failing:

  

  Here is the docker run command or docker-compose.yml file I used to start n8n: (Paste your command or the contents of your docker-compose.yml file here)

  Thank you for any help you can provide!

Hey @DHANYA_SHRUJANA hope all is well. Welcome to the community.

This would typically happen when you try to reference a webhook url of a workflow which isn’t running. I see you are using the test url, which means that you would need to go to that other workflow and execute the workflow:

This way the webhook will get registered and should be able to answer.
