Hello, SOMEONE CAN HELP ME PLEASE!

I'm currently running a production deployment of n8n v1.94.0 on Railway under the project balanced-courtesy. I've followed all the necessary steps to expose production webhooks correctly:

1. Successfully deployed the n8n instance.

2. Set the environment variable WEBHOOK_TUNNEL_URL=https://n8n-production-db8a.up.railway.app.

3. Enabled basic authentication.

4. Activated the workflow and the webhook in n8n.

5. Made multiple deployments and restarts to ensure the environment was properly refreshed.

Despite this, the Production Webhook URL always displays http://localhost:5678/... inside the n8n interface, and webhook POST requests return this error:

The requested webhook "POST activar-mcp" is not registered.
Hint: The workflow must be active for a production URL to run successfully.

This suggests n8n is not registering the webhook in production mode, even though the workflow is active and deployed, and WEBHOOK_TUNNEL_URL is set.

Can someone please check if there's something wrong with how Railway is passing the variable into the container? Or confirm if a specific build/restart method is required to make the webhook production URL take effect?

Thanks for your help.

Best regards,
Dietrich Truchsess
