Docker-Compose Webhook Not Working: Permissions/Environment Issue?

[Exnav29]

Describe the problem/error/question

I’m using n8n in a Docker-Compose setup with NGINX as a reverse proxy. The editor loads fine at the configured URL, and workflows can be activated, but webhooks do not respond to test events sent to the expected URL.

---

What is the error message (if any)?

There’s no direct error visible when testing the webhook, but the following logs were captured:

• n8n Logs:

csharp

Copy code

Error: nodes package n8n-nodes-base is already loaded.
Please delete this second copy at path /home/node/.n8n/nodes/node_modules/n8n-nodes-base

• NGINX Logs:

csharp

Copy code

recv() failed (104: Connection reset by peer) while reading response header from upstream

---

Please share your workflow

Here’s a simple workflow with a webhook trigger for testing purposes:

json

Copy code

---

Share the output returned by the last node

When testing the webhook, there’s no response from the endpoint, and no logs are triggered in the n8n editor.

Information on your n8n setup

Additional Details

Here’s the docker-compose.yml file (sanitized):

Here’s a snippet of the NGINX configuration for the proxy (sanitized):

Hi @Exnav29

I have tried this in the past and had it working but needed to at the webbook and webhook-test as locations in the nginx config file.

Example below:

server {
    listen 80;
    server_name <your-domain>;

    location / {
    proxy_pass http://127.0.0.1:5678;
    proxy_set_header Connection 'Upgrade';
    proxy_set_header Upgrade $http_upgrade;
    proxy_http_version 1.1;
  }

    location /webhook/ {
        proxy_pass http://localhost:5678;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }

    location /webhook-test/ {
        proxy_pass http://localhost:5678;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }

    # Error Pages
    error_page 500 502 503 504 /50x.html;
    location = /50x.html {
        root /usr/share/nginx/html;
    }
}

Then restart nginx and docker.
